Here are boutique hotels in the U.S. that are known for on‑site art galleries or substantial, curated art programs you can visit as a non‑guest:

• 21c Museum Hotels (multiple U.S. cities: Louisville, Cincinnati, Bentonville, Durham, Lexington, Chicago, St. Louis, Nashville, etc.) — each property is a boutique hotel + contemporary art museum with free, rotating exhibitions and museum‑grade gallery space open to the public. (21cmuseumhotels.com)

• The Betsy, South Beach (Miami, FL) — a boutique hotel that functions as a local arts hub with multiple rotating galleries and permanent collections (photography, sculpture, public‑art installations) and a longrunning arts/residency program. (miaminewtimes.com)

• Ace Hotel properties (examples: Ace Brooklyn, Ace Chicago, Ace New York) — Ace hotels often feature dedicated gallery spaces and a robust rotating exhibition/program schedule showcasing local and contemporary artists. (Several Ace locations list “Gallery” or regular exhibitions in their public‑space programming.) (findhotels.nyc)

If you’d like, I can:

• Find hotels with galleries in a specific city (e.g., New York, Los Angeles, Miami, San Francisco), or
• Give links, current exhibitions, visiting hours, and whether the gallery is open to the public (not just guests).

Which city or region do you want options for?
