I did a quick forum search but didn't get too much detail. We leave on our DCL Dream cruise on the 28th. Right now, the only thing we have schedule on Castaway Cay is the glass bottom boat tour. We have three kids aged 2-5. Is this excursion worth it? I read in the DCL Passporter that the boat is crowded and the glass is scratched and cloudy. Should we just cancel this and enjoy the beach? Thanks for your help!
