Rambutan Hotel with locations in Siem Reap and Phnom Penh is gay owned and managed. No problems or fees with joiners and as long as they have proper ID that must be presented at the front desk. Staff is great at both hotels and many of staff are local gay Cambodians but not available to take to your room. The staff and managers can help with gay bar information, transportation, tours, etc. You will need to see if they have rooms that meet your need and in your price range as prices change with seasons. Hotel guests are gay and straight but you will likely find fellow gay travelers to chat with at the hotel bar.
