We’ve actually never done a
DCL excursion until our November Eastern coming up in 19 days, our DS is 6 and won’t be fully vaccinated so DCL excursions are a must. We are doing snorkeling in St Thomas as well and can let you know how that goes.
As far as I know, Aristocat isn’t a Disney Vendor for excursions, at the time we used them, they had lost one catamaran to Hurricane Irma, and were in the process of buying another. On our trip it was only DCL folks, there was one other MSC ship in port that day, but we didn’t have any of their pax on our Catamaran. Back then they limited capacity to about 20 people, as the boat fit 35-40 but they want everyone to have space and enjoy themselves. I’d say it was maybe 3 or 4 families and about half were kids 12 and under.
In St Thomas we are doing one of the Shipwreck Cove snorkeling tours and can report back on how that goes when we are back on 11/21!
