The Gran Palladium Colonial and Kantenah has large river like pools.
The Grand Sirenis below is a new entry into the Mayan Rivieria and has a very unique building style. Don't stay there if you don't like angles.
They have a number of small beaches and secluded coves great for snorkeling.
While the Gran Gahia Principe is further south, closer to Puerto Adventuras, the beach is very nice.
Hope to see you here soon!
