Dear Jean,
Regarding diving gear- did I tell you Mark is a scuba diver?! So if you like you can borrow one of his wetsuits or dry suits and whatever else you need to accesorize yourself?
There are diving masks (although the little boys are partial to them in their baths! LOL), flippers, tanks, snorkles, oxgyen (although that may have been used up!)...just ask! It's a nice dark blue colour..
Love,
Amanda
