I was just wondering how much cash I should take to discovery cove for extra's such as drinks and snacks for the kids. We are going on the 31st Aug and I imagine with the heat we will need to drink quiet alot, and I am sure the kids will need to have a snack in the day. I know you get a lunch included in the admission price, but am unclear what else is included. Any help and advice would be greatly appreiciated for a first timer.
