Serenity Eco Luxury Tented Camp is a 'glamping' style hotel in Xpu Ha. It is not all inclusive.
If you do decide to go to an all-inclusive hotel and are traveling with other adults, I would recommend scoping out an adults-only property. Where we stayed was adults only, however we visited their sister property while in Mexico and it was very family focused.
I can’t stress enough the importance of checking reviews for hotels online. My go-to website for reviews is TripAdvisor.
