I tend to buy one of the ones they sell at the water parks.Thet are a little card that you put around your wrist on a bracelet.Saves carrying cash and cards about BUT I also bought one of the card holders that you put around your neck so when on
DDP or visa card can carry on you and they dont get wet at all.Like tiggs says you have to buy them there and load them as and when. I am going to get DD one as she likes using my Visa card toooo much


along with her own DDollars.
