Sheraton's Check-In Age: Set Property-by-Property, Not by Marriott Corporate

Marriott, which owns Sheraton, does not impose a single minimum check-in age across the brand. Instead, the age requirement, along with deposit amounts and any extra ID rules, is decided by each individual hotel. This is why you can find two Sheraton-branded hotels in the same metro area with completely different rules for guests under 21. If you're asking "does Sheraton allow 18-year-olds to check in," the honest answer is that it's a per-property policy, and you need to verify it for the exact hotel you plan to book.

Downtown Flagship Sheratons Skew Toward 21+

Sheraton is Marriott's full-service, often big-city and convention-hotel brand, and that positioning matters for age policy. Documented reporting on Marriott's portfolio shows that flagship downtown properties — the category Sheraton overwhelmingly falls into — more commonly require guests to be 21 or older to check in, similar to Renaissance, JW Marriott, and Ritz-Carlton. This lines up with the general industry pattern of large urban and convention hotels tightening age minimums to manage liability around large groups and events. Suburban or smaller-market Sheratons are more likely to allow 18-year-olds, but this varies by individual property and should be confirmed directly rather than assumed.

Active-Duty Military ID Exception

Marriott honors a military exception across most of its brands, including Sheraton: active-duty service members 18 and older can typically check in regardless of a property's standard age minimum when they present a valid military ID. A number of states also have statutes requiring hotels to waive minimum-age rules for service members traveling on official orders. Because this is administered at the property level, if you're under 21 and on orders, call the specific Sheraton ahead of time and ask them to note the military exception on your reservation.

Deposits and Incidental Holds

Not publicly documented at the brand level. Sheraton does not publish a fixed incidental or security deposit amount that applies across all locations. As a larger, full-service hotel, expect the hold to potentially be higher than a limited-service property, but the actual figure is set by the individual hotel — ask the front desk or check that property's listed policy before you travel.

How to Book a Sheraton at 18 Without Getting Denied at the Desk

Because Sheraton is one of the brands more likely to require 21+, an 18-year-old traveler should take extra steps before locking in a reservation:

  • Call the exact Sheraton property directly and ask for its minimum check-in age in plain terms — don't rely on the brand's general reputation.
  • Ask whether the requirement changes for weekends, holidays, or convention dates, since some downtown properties tighten rules during high-risk periods.
  • If active-duty military and under 21, mention it during booking and again at check-in with your ID ready.
  • Bring a valid government-issued photo ID and a credit or debit card in the guest's own name.
