We may be coming to the reef area in Nov. (is this a good time to come?) with our 10 yr. old daughter. Good snorkelers, not divers. Do people ever go on a boat for 3 to 7 days and snorkel from place to place sort of like in the Galapagos? A smaller boat with no more than 15 or 20 people? Or is staying on dirrerent islands the best thing? If so, which islands have the best snorkeling if we wnated to focus on that and where would one stay if we wanted to avoid big resort type places and stay at modest uncrowded places? Thanks a lot.
