S.H.
I enjoy the Rivera Maya area. We've stayed at Dreams Tulum (would not recommend, seaweed in most areas of water, rocky beach in parts too. Did have tasty food.), Grand Palladium twice (5 resorts in one, 2 adult sections, we stayed in the nicest part Royal Riviera - incredible cabana room, deluxe bath, outdoor shower *sigh* but be prepared to walk to the other side of the resort since it's a pretty secluded adult section. There are staff with golf carts that happily take you wherever you want to go. Also stayed in the Kantenah section and it was OK but not romantic, more a family trip area) and last year we were at the adult section of IberoStar Grand Hotel Paraiso (wonderful room, beautiful beach, food not as good as GP.) Avoid the IberoStar Cozumel unless all you want to do is scuba. It's a bit worn down.
