Guests arriving with more people than reserved: what to do and how to prevent it

Guests book for 2 people. You check the building's camera and see 5 people get out of the car. Sounds familiar, right? This is one of the most common problems in tourist rentals in Spain, and if not managed properly, it can lead to extra wear and tear, neighbor complaints, issues with the traveler registry, and even fines. In this guide, we tell you how to detect it, what you can do legally, and how to prevent it from the first message.

Why does it happen (and why is it a serious problem)

Guests bring extra people for three main reasons:

• To save money: if you charge per person or have a surcharge for additional guests, they lie to pay less.
• To sneak in more people than the maximum occupancy: they reserve an apartment for 4 knowing it will be 6 because they couldn't find anything larger.
• Impromptu party: they arrive with 2 but by the second day, friends with suitcases appear.

And it's not just about money. You face real issues:

• Wear and tear: more people = more consumption, more cleaning, more laundry, more wear on mattresses and sofas.
• Safety: if your apartment is licensed for 4, it complies with regulations for 4. Allowing 6 may invalidate your license.
• Neighbors: more people = more noise, more elevator use, more complaints. And you know how that ends (neighbor complaint management).
• Traveler registry: you only have data for the people who booked. If the Civil Guard arrives and there are 6 in the apartment but only 4 registered, you face trouble.

What the law says (practical summary)

In Spain, the maximum occupancy of a tourist accommodation is set by the license and depends on the autonomous community. Generally:

• It is calculated based on the number of beds or approved places, not square meters.
• You cannot admit more people than your license allows, even if asked to do so.
• All guests over 14 years old must be registered in SES Hospedajes (more info in minor registration).

If you accept more guests than your license permits, you risk sanctions ranging from 600 to 30,000 euros depending on the community, even if the guest lied to you. The responsibility is yours as the owner.

How to detect if more than the reserved number are coming

There are signs that can be seen even before check-in:

Before booking

• They ask "if someone else can fit on the sofa".
• They book a 3-bedroom apartment for 2.
• The price per person seems "a bit high" and they haggle a lot.
• They refuse to give names of other guests.

During check-in

• They arrive with more suitcases than appropriate (rule of thumb: 1 large suitcase per adult).
• They park two cars despite having booked for 2 people.
• "Some friends are coming to visit us for a while" (spoiler: they stay overnight).

During the stay

• Electricity or water consumption is much higher than average.
• Neighbors notify you about noise or a lot of people entering and leaving.
• Excessive used towels or sheets during change.
• Excess garbage.

What to do if you detect extra guests

It depends on when you catch them and how many they are. It's not the same a friend who came for dinner as 4 people sleeping in the living room.

Option 1: Charge the surcharge

If your policy already includes a price for additional guests and there are few extras, the most pragmatic approach is to charge the difference and register them. Write something like:

"Hello X, we saw that there are more people than booked. No problem, but I need to register everyone and adjust the price according to our policy (X euros per extra person/night). Can you send me the details?"

Straightforward, without drama, without accusations.

Option 2: Reject the excess

If it exceeds your license's maximum occupancy, you have no choice: you cannot accept them. Explain calmly:

"The property is licensed for a maximum of X people according to regulations. I cannot allow more to stay; it's a legal issue and I risk sanctions. The extra guests will need to find another accommodation."

Option 3: Cancel and evict

If they blatantly lie, refuse to pay the extra, or there's a party, you have the right to cancel the reservation. Document everything (photos, messages, witnesses if possible) and contact the platform immediately. Airbnb and Booking usually support hosts if there's clear violation of rules and evidence.

How to prevent it from the start

1. Leave your policy very clear in the listing

Explicitly state:

• Maximum number of guests.
• Surcharge for extra person (if applicable).
• Prohibition of visits that stay overnight.
• Consequences of violation (cancellation without refund).

2. Ask for the names of all guests before check-in

Mandatory for SES Hospedajes and also a strong deterrent against "sneaking" people in. Inform them that you need ID for everyone; many think twice. Having a good automated check-in process helps.

3. Price structure per person

If you charge a fixed price up to X people and a surcharge for each additional, you reduce negative incentives. Example:

Price setup	Risk of extra guests
Fixed price up to maximum occupancy	High (they don't pay more even if they add people)
Base price + surcharge per person	Low (it's expensive to sneak in extra people)
Price per person from the first guest	Medium (they lie in the reservation)

4. Use outdoor sensors and cameras (properly)

A noise sensor like the ones we mention in noise sensors or an outdoor camera provides information without invading privacy. Remember: inside the property, cameras are NOT allowed, and outdoor cameras must comply with AEPD regulations.

5. Sufficient deposit

A well-structured deposit policy covers extra wear and tear and gives room for negotiation if there's non-compliance.

6. Contact with neighbors

Your neighbors are your best allies. If they have your phone number and know you respond quickly, they'll alert you to suspicious activity. Better that than a police call.

How much to charge per extra guest

It depends on your area and type of property, but as a rough guide:

Property type	Typical surcharge per person/night
Standard city apartment	15-25 euros
Family/rural home	20-35 euros
Villa or luxury property	40-80 euros

This amount should cover extra consumption, additional laundry, increased wear, and compensate for risk. It's not about charging just to charge.

The case of babies and small children

Many owners do not count babies (under 2-3 years) sleeping in a crib in the maximum occupancy. It's your decision, but make it clear in the listing to avoid misunderstandings. Remember that children under 14 do not register in SES Hospedajes but do count towards the actual occupancy.

What NOT to do

• Make a scene at the door: you'll definitely lose your review.
• Accuse without proof: if you're wrong, you'll face the consequences.
• Enter without warning to check: invasion of privacy and may be a crime.
• Cut WiFi or electricity as "revenge": exposes you to charges of coercion.
• Ignore it and move on: you accumulate wear and tear, neighbor problems, and legal risks.

How Autoregistro fits in

One of the moments when you detect a "phantom guest" is during the traveler registration. If you ask for everyone's data before check-in and only get 2 out of 5, that's a red flag.

With Autoregistro, you send a link to the guest who booked, and they (and all companions over 14) fill out a form with their data. Everything goes directly to SES Hospedajes without you touching anything. It costs 1 euro per month per property, less than a coffee. If suddenly only 2 people are registered but the reservation was for 4, you already know something's wrong before they arrive.

Frequently Asked Questions

Can I refuse entry if there are more than booked?

Yes, if it exceeds your license's maximum occupancy. You're legally obliged not to accept them. If the excess is small and within your license, you can charge a surcharge and register them.

What if visitors come but don't stay overnight?

It depends on your policy. Many owners prohibit it outright to avoid noise and neighbor disturbances. If you allow it, set a time limit (e.g., until 10 pm) and a maximum number.

Can the authorities fine me if I have more guests than allowed even if I don't know?

Yes. As the owner, you're responsible. That's why it's so important to keep the traveler registry up to date and verify who actually enters the property.

Should I register in SES Hospedajes guests who only stay for the afternoon?

No. SES Hospedajes only requires registration for overnight guests. Visitors who don't sleep don't count.

Does Airbnb support me if I evict guests for bringing more people?

Generally yes, if you have proof (photos, messages, outdoor cameras) and your guest policy is clear in the listing. Contact support before taking drastic action and document everything.
