Catdancer - we will also be there in May on a 52 Lagoon. We have 10 people (6 staterooms sort of), but never thought to get second dingy. We will have 4 inflatable paddle boards, so if someone really wants to get to shore, there's always a way. This is our 4th trip with this group - 2 familys with a total of 5 20 somethings. Everyone loves this trip, and a second dingy has never been something we've needed in the past.
