FAQs
1) What is the minimum age to check into a hotel?
The minimum age for hotel check-in varies by location and property. Generally, most hotels require guests to be at least 18 years old to check in. However, most hotels may have a minimum age of 21, particularly in certain areas like Las Vegas or resorts with adult-oriented amenities. This is what we do best, we curate a list of hotels that allow under 21 years or age to check-in.
2) Do I need to show an ID when checking into a hotel at 18?
Yes, hotels typically require guests to present a valid government-issued photo ID (such as a passport, driver’s license, or national ID card) upon check-in to verify age and identity. This ensures the hotel complies with local regulations and verifies the booking details.
3) Can I book a hotel room online at 18?
Yes, you can book a hotel room online at 18, provided the hotel allows check-in for guests under 21. While we do our best to verify this information and only show hotels that allow under 21 to book, the hotels set the policies and they are subject to change, so it's best to verify on their age policies on the booking page.
4) Are there hotels that specifically cater to 18+ guests?
Yes, many hotels are welcoming to guests 18 and older, especially those in major cities, tourist areas, or university towns. These hotels understand the needs of young travelers and typically don’t have age restrictions beyond the minimum check-in age.
