Will I need an I.D. to check in as an 18-year-old?

All hotels require the guest checking in to have a valid form of identification, regardless of age.

Will I need a credit card to check in as an 18-year-old?

It is common practice to present a credit card to check in to a hotel. While some hotels accept debit cards or cash, it isn’t typical or standard.

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

It is legal for an 18-year-old to check into a hotel in Colorado. However, some places require a guest to be 21 years of age instead.

Why do most hotels in Colorado have an age requirement of 21?

When it comes to the age requirement, hotels have the final say. Sometimes, their insurance plan won’t allow guests under 21 to check in, and some hotel owners see it as a liability.

Alternatives to Hotels for 18-Year-Olds

Finding a hotel that allows guests under 21 to check in for a night can be challenging. However, if you find yourself in this situation, you can rest assured that other options are available.


Having exploded in popularity in recent years, using Airbnb has become more common when visiting a new area. You can search for a home or apartment that meets your needs and reserve it for the dates you like. 

It’s worth noting that some residences on the Airbnb website require the owner to approve the reservation before check-in. Therefore, if you plan to book something last minute, be sure that prior approval isn’t a requirement.

Youth Hostels

If you are looking for a budget-friendly option, booking a space at a local hostel is a good option. Many have separate rooms or bunks that give you storage and privacy. Additionally, you often have access to a communal kitchen and bathroom.

Because of the cheap price point, hostels tend to fill up fast. Be sure to call in advance to guarantee a room or bunk.


A newer trend among the younger crowd is renting a campervan to explore as you go. These vans have a bed and a small kitchenette in the back, so you can stop anytime to rest. 

Before reserving, plot out your approximate stops and determine the costs ahead of time for campgrounds. You can also find free places to park overnight.
