Minimum Check-In Age at Every Major U.S. Hotel Chain (Live Data)

This is the chain reference. Two columns matter: what corporate publishes (the policy on the chain's official site) and what we observe (the share of indexed properties with a confirmed minimum check-in age of 18). They often disagree, and the gap is the whole point of this site.

The data below is from our index of about 9,900 U.S. hotels as of April 2026. We've confirmed minimum-check-in-age data on roughly 5,600 of them — the rest are still being verified by our scraper.

The summary table

Chain	Published	Indexed	Verified 18+	18+ rate (of verified)	Detail
Motel 6	18+	56	41	85%	→
Hyatt	18+	78	23	36%	→
Red Roof Inn	18+	27	7	26%	→
Wyndham (parent)	21+	168	33	24%	→
Choice Hotels	18+	111	21	23%	→
Marriott	21+	474	70	20%	→
Best Western	21+	48	6	19%	→
Hilton	21+	382	58	18%	→
IHG	18+	202	29	17%	→

Reading this table:

• The chains that are reliably 18+ on the ground: Motel 6 is the only one in our data that approaches a "yes most of the time" rate (85%). Everything else is more variable than the chain's marketing implies.
• Hyatt's 36% surprised us most. Hyatt publishes a corporate 18+ minimum, but only 36% of indexed Hyatt-family properties have a confirmed 18+ policy. The rest are 21+. That's a meaningful gap between the corporate policy and what an under-21 traveler actually encounters.
• IHG (Holiday Inn family) is the second-biggest gap. Published 18+, observed 17% — most indexed IHG properties end up at 21+ in practice.
• The 21+ chains hold 21+ in practice. Marriott (20%), Hilton (18%), Best Western (19%), Wyndham parent (24%) — none of them broke through 25% 18+ adoption across our index. The audit-era assumption that "franchisees override the chain default" turns out to be true at small scale, not large.

What this means for an under-21 traveler

If you're searching a specific city:

1. Default to Motel 6 if it's in the market and the budget tier works. It's the only chain whose published 18+ policy is consistently honored at the property level.
2. Don't assume Hyatt = 18+ despite what their corporate page says. About 2/3 of Hyatt properties in our data enforce 21+ at the front desk regardless of the chain default.
3. Don't bother trying at Hilton flagships, Marriott flagships, full-service IHG (Crowne Plaza, InterContinental), or Best Western premium tier. Our data shows these as overwhelmingly 21+.

For the per-chain city-level breakdowns (which Hyatts in Phoenix are 18+, which Hiltons in Miami, etc.), follow the chain links in the table — each chain page has a city-by-city sortable table.

Methodology

• Indexed: the count of U.S. properties for that chain in our hotel index.
• Verified 18+: properties whose minCheckinAge field has been confirmed at 18 by our scraping pipeline.
• 18+ rate: verified 18+ ÷ (verified 18+ + verified 21+). Excludes properties whose age policy is still pending verification (about 40% of our index).

The data refreshes as the scraper indexes new cities and re-verifies stale records. The chain pages above use a 1-hour cache; if you see numbers that look off, they'll re-sync within the hour.
