I'm interested in doing both the Blue Lagoon Dolphin Swim and a snorkeling trip (either the Caribbean Queen or the Catamaran Sail and Reef Snorkeling) when the Disney Dream docks in Nassau during our 3 night cruise. Is there time to do both activities? Any downside to trying to do them both in one day? Will we be missing other things? Would we still have time to walk around Nassau at all? Thanks!
