A suite with very large rooms, full kitchen, huge Jacuzzi tubs, Spa services, in room messages, full maid services, room service, concierge, so many pools, the Monday night fiesta.
The turquoise Caribbean, Mayan ruins, adventure parks, like Xplore, diving and snorkeling off of Cozumel, shopping (and bartering) in Playa del Carmen.
So much for all the family to do. In a place big enough and varied enough to do it together.
