To stay at a hotel by yourself, you generally have to be at least 18 years old, though plenty of hotels set their minimum at 19, 20, or 21. No federal law establishes a check-in age. Each property writes its own policy, and those policies can differ between chains and even between two hotels flying the same brand flag. Confirming the rule at the specific hotel you want to book is the only reliable way to know before you arrive.
Why the Minimum Age Varies
Checking into a hotel means signing a registration agreement, which is a contract. In most states, people under 18 can walk away from contracts they sign, leaving the hotel with little recourse for unpaid charges or damages.1Legal Information Institute. Voidable That’s the baseline reason for the 18-year floor.
Hotels that set the bar at 21 are usually thinking about alcohol. Properties with minibars, on-site bars, or casinos face extra exposure when guests are old enough to sign a contract but too young to drink legally. Raising the check-in age to 21 sidesteps that risk. Concerns about noise and property damage from younger guests factor in too, though hotels rarely say so in writing.
What the Major Chains Require
Even within a single brand, the minimum can shift from one location to the next. Here is what the largest chains publish at the corporate level:
- Marriott. The minimum check-in age “is set by the Hotel.” Many Marriott, Courtyard, and Residence Inn locations allow check-in at 18, but some require 21.2Marriott. What Is the Minimum Age Required to Check-In?
- Hilton. The minimum age varies by property. Hilton points travelers to the specific hotel’s “All Policies” page for the answer.3Hilton. Hilton Hotel Policies
- Hyatt. Generally requires guests to be 21, though this can vary by hotel. Someone meeting the minimum must be present at check-in and registered to the room.4Hyatt Hotels and Resorts. Reservation Frequently Asked Questions
- Choice Hotels (Comfort Inn, Quality Inn). Most properties require solo guests to be at least 19, and some require 21. When two or more guests share a room and any occupant is under 18, at least one person must be 21 or older.5Choice Hotels. Choice Hotels FAQs
- Wyndham (Days Inn, Super 8, La Quinta). The minimum age “varies by hotel,” and the corporate FAQ tells guests to call the property directly. Many Wyndham-brand hotels allow check-in at 18.6Wyndham Hotels. Frequently Asked Questions
Budget and economy chains such as Motel 6 and Red Roof Inn tend to be friendlier to 18-year-olds, largely because they don’t run minibars or lounges. Boutique hotels and resorts skew toward 21 and up. The pattern is loose enough that brand alone isn’t a safe assumption.
How to Confirm the Age at a Specific Hotel
Call the property before you book. Corporate pages for Marriott, Hilton, and Wyndham all say the age policy is set at the individual hotel level, so no chain-wide FAQ can answer for a particular address. A two-minute call to the front desk is the only source that counts. Ask directly: “What is the minimum age to check in at this location?”
If you prefer to check online, look for the hotel’s “Policies” or “FAQ” page on its own website. Third-party sites like Expedia and Booking.com sometimes show a hotel’s rules and restrictions, but age requirements are often buried or missing. Expedia’s terms note that the travel provider’s rules and restrictions apply to your booking and put the responsibility on you to verify the specifics.7Expedia. Terms of Service Booking through a third party without confirming age is how young travelers most often end up stranded at check-in.
What You Need at Check-In
Meeting the age requirement is the first step. You also need two things at the front desk:
- A government-issued photo ID (driver’s license, state ID, or passport) whose name matches the reservation and whose birth date confirms you meet the minimum.
- A credit or debit card in your name for the incidental hold the hotel places at check-in to cover charges like room service or minibar use. The hold is separate from the room charge and clears after checkout, though it can take several business days.8Marriott. What Is an Incidental Hold?
The incidental hold is where younger travelers most often get caught out. Debit cards are accepted at most properties, but the hold pulls real money out of your checking account instead of reserving credit. A hold of $50 to $200 per night can leave a tight travel budget short until the funds release. Some hotels also require a larger deposit for debit users. A credit card sidesteps the problem because the hold doesn’t touch your cash.
Options If You’re Under the Hotel’s Minimum
If you’re 18 to 20 and the hotel you want requires 21, you have a few options beyond changing hotels.
Ask About a Parent’s Credit Card Authorization
Some hotels let a parent complete a third-party credit card authorization form so the parent can guarantee payment without being present. The form usually asks for the cardholder’s name, card details, the guest’s name, arrival and departure dates, and a spending cap. Not every hotel accepts these forms, and the guest checking in still has to meet the property’s minimum age even with a parent’s card on file. Call first and ask whether the hotel accepts third-party authorizations and whether doing so changes the age rule for the person on-site.
Have an Older Companion Check In
The most reliable workaround is having someone who meets the age requirement register as the guest, sign the agreement, and put their card down. Policies vary on whether that person has to stay for the whole trip, so ask before you count on it.
Pick a Chain That Takes 18-Year-Olds
Rather than fight a 21-and-over policy, book with a brand that welcomes younger adults. Budget and midrange chains set the minimum at 18 more consistently than upscale brands.
Consider a Short-Term Rental
If traditional hotels aren’t working, short-term rental platforms may offer more flexibility. Airbnb requires all users to be at least 18 to create an account and book a stay, though individual hosts can set their own house rules and may decline younger guests.9Airbnb Help Center. Age Requirements VRBO similarly sets its minimum at 18, with owners able to require an older renter but not a younger one. The tradeoff: no front desk if something goes wrong, cancellation policies that vary by host, and damage deposits that can run higher than a hotel’s incidental hold.
Military ID and Emancipated Minors
Active-duty service members under 21 run into age policies constantly, and the industry’s response has been uneven. Some chains have internal policies waiving age requirements for guests with military ID, but front desk staff don’t always know about them. Florida passed a law in 2015 eliminating hotel age requirements for anyone with active-duty military identification. If you’re turned away, ask for a manager and show your military ID; the corporate policy may be more accommodating than the clerk realizes.
A minor who has been legally emancipated by a court has the same contract capacity as an adult, which in theory lets an emancipated 17-year-old sign a hotel registration as validly as any 18-year-old. In practice, front desk systems check the birth date on your ID, and few staff are trained to recognize emancipation orders. Bring the court order, call ahead to explain, and expect better luck at independently owned properties or smaller chains where a manager can override a blanket age rule.
If You Get Turned Away
A hotel enforcing its age policy will simply refuse to give you a key, and front desk staff generally can’t make exceptions. The bigger sting is financial: if you booked a non-refundable rate or used a third-party site, you may lose the entire prepayment, because most cancellation policies don’t carve out guests who show up and can’t meet check-in requirements.
If it happens, call nearby hotels to find one with a lower age requirement, or contact a parent or guardian who can book by phone and provide card authorization. The whole scenario is avoidable with one phone call before you book.
