In reading thru the itinerary it looks like most days on board the ship there are 4 different excursion choices. Some short (under 2 hours) and others half or more of a day. Is the timing of the different choices such that you could do more than one per day or are you limited to just one choice? While the ship looks nice, if we took the tour we'd want to see as much as possible of each Island not just sitting in the ships lounge.
