We’re torn between a 7 night on fantasy stopping at Tortuga, St. Thomas and Castaway Cay or a 5 night on magic going to key west, Nassau and castaway cay. $2700 more to do 7 night. We have two boys, 8 and 5. Can’t decide if we’ll regret not doing the 7 night if we do the five or if the 7 night would be too long. Anyone made a similar decision and have thoughts?
