The thing to note is, depending on which cruise you are on, you may only have two days where you would be rushing for 6:00 PM Supper (in our case Key West - 7:30 PM on board and Cozumel - on board at 6:30. The other days (Grand Cayman and CC), if we stayed off till 1/2 hour before Early Supper, we would have missed the ship! So I guess, it may only affect 1 possible excursion for some people. I don't live and die by excursions, as eating closer to 6:00 PM for our two families is more important. In planning out this cruise for my family and advising the family we are travelling with, I thought with the 3 kids especially, we are all used to eating early Supper- 8 or 8:30 PM is just way too late!
