I'm looking to go to a few places to go snorkeling with my two children (11 and 15) on the cruise ship days, so that we can avoid the cruise ship madness. looking for easy get-aways, either swim in from shore or quick boat ride out. how easy is this to arrange? if this is not possible I think we will be vacationing elsewhere, as it sounds absolutely dreadful to be there on cruse ship days. any comments with regards to this are welcome!
