How Old Do You Have to Be to Rent a Hotel Room in Idaho?

You must be at least 18 years old to rent a hotel room in Idaho. This is the law in the United States, and all hotels follow this policy.

Some hotels create extra guidelines regarding check-in age requirements. These private guidelines often extend the check-in age to at least 21 years old to rent a room.

Why is the minimum age to book a hotel room 18 in Idaho?

You have to be at least 18 years old to stay at hotels by yourself for several reasons.

Purchasing and booking a hotel room is a responsibility requiring contracts and prerequisites, most of which minors cannot legally agree to.

Hotels would be responsible for the safety of anyone under 18. They would also be liable for any damages and fees incurred by the minor.

Alternatives to Hotels for 18-Year-Olds

Below are three excellent hotel alternatives for 18-year-olds.

Youth Hostels

Youth hostels offer a cost-effective place to stay on your trip versus a hotel room. Unlike hotels, these hostels provide opportunities specifically for younger people.

The only downside is that you might have to share your space with others in a communal space rather than the privacy of a hotel room.


Airbnbs provide room for lots of traveling flexibility. Book a room for one person or a house for you and your group.

Most Airbnbs allow 18-year-olds, but age requirements vary depending on the host.


Camper vans are a significant investment for frequent travelers. Though, with insurance and gas, they can get a little pricey.

Try out an R.V. rental service instead. Age requirements differ, but some agencies allow 18-year-olds.


Here are answers to frequently asked questions about renting hotel rooms and age requirements.

Will the hotel check my I.D. as an 18-year-old?

Yes, hotels always check your I.D., no matter your age. Hotels use your I.D. at check-in to confirm your information matches what they have on file.

Do I need to bring my credit card to check in as an 18-year-old?

Yes, bring the credit card you booked for the hotel room to check-in. The hotel attendant will use this card to verify your room.

Is it legal for an 18-year-old to check in to a hotel in Idaho?

Eighteen-year-olds can check into any hotel in Idaho except those with a 21-year-old age requirement.

Why do some hotels in Idaho have an age requirement of 21?
