Can you book a hotel at 16 in Spain?

1.9 You must be aged 18 years old or over to make a booking with us and you must be aged 18 years old or over to stay alone.



Generally, the legal age to book a hotel room in Spain is 18 years old. Most hotels require a valid ID (passport or national ID) at check-in to comply with national security laws that mandate the registration of all guests. If you are 16 or 17, you typically cannot check in alone unless you have a notarized letter of consent from a parent or legal guardian, and even then, many hotels have internal policies that strictly forbid solo minors. However, some youth hostels or specific "youth-friendly" hotel chains like MEININGER may allow 16-year-olds to stay in private rooms if they provide a signed authorization form and a copy of their parent's ID. In 2026, it is essential to contact the property directly before booking; if you show up as a 16-year-old without an adult or the proper legal documentation, the hotel is legally obligated to refuse you, and you may find yourself without a place to stay in a foreign country.

Before you even consider whether you have to be 21 or 18 to check in, you may be wondering why there's even a restriction on how old you need to be to book a hotel. U.S. hotels restrict travelers to a minimum age of 18 because your check-in is the equivalent of signing a contract.
