JW Marriott Cancun -- a top end property with endless pools, poolside bars, great food, and direct access to the white sand beach.
To give you an idea of how thorough the service is -- they employ a falconer to chase away other birds from the pool and beach area. I didn't see one seagull while there.
What I especially appreciate is that they don't nickel-and-dime for minor things. Even a basic room -- quite reasonably priced -- gets free water bottles and coffee replaced each day. The bars, restaurants, and shops don't overcharge like other on-prem retailers at other hotels.
