Hiya, we're booked to go in September as I was wondering whether we can use our own sunscreen as we're not having the dolphin swim? Or still have to use theirs?
Unless you plan to also avoid the Grand Reef and the new Freshwater Oasis (assuming it is open by September....and it better be because I'm going on August 29th!!! ) then I would say you would still have to use DC's sunscreen. Both the reef and the freshwater oasis also have live fish and animals that could be affected by the chemicals in regular sunscreen.
Or that's my guess, anyway. I am sure someone will correct me if I am mistaken!
The dolphin experience has nothing to do with it. You get the sunscreen in your bag when you pick up your snorkel/mask. You use those everywhere BUT the dolphin experience.
