Best hotels in Cuba or Dominican?

Booking a destination wedding, but looking for some input on great resorts. I have been to a few that show up on the top of the list i.e Grand Memories Varadero, Diamond Club, and it was disappointing. We have traveled to the Luxury Bahia Principe Bouganville for a wedding and it was absolutely beautiful, however the water was really murky because of the river near by. If the water was clear and great for snorkeling at the Bahia Principe Bouganville it would be the perfect place to go back to. Clear water for snorkeling at the hotel is a must. My fiance has only ever been to the two hotels I have mentioned and both trips snokeling was a flop. Grand Memories had giant (but fun) waves. Anyone been to a great resort with good snorkeling right at the beach? Thanks
