The suits are VERY nice on the PG. They even have the Regent logo on the chest, so you will look official while you are in the water..... Yes it was warm enough to snorkle just with your swimsuit in BB. I guess it depends on the weather and how much you kick and how long you are in the water too. If you are worried, just check out a wetsuit. No need to pack one and worry about it drying, etc.
