Before I reserve this - DH wants to snorkel, I do not. If we get the package for him can I use his float while he snorkels? Or do they give you an armband or something? Can he just pick up the float before he goes snorkeling and give the float to me? Do you have the float the entire time? What about the bikes? I wasn't planning on reserving bikes, but it seems silly not to reserve the whole package if you plan on both the snorkel and the float. Thoughts? Thanks!
