Yes...you can bring in snacks and drinks...just no glass. Your best bet would be a back pack that can be easily carried.Just wondering if there are any food/drink restrictions on what you can bring into the park? My kids never want to stop for lunch, they'd rather just eat a snack and then have an early dinner when we go to places like this!
Universal and Disney sell Coke products in the parks and Sea World sells Pepsi products.I've had comments about the drinks at Disney, too, but they don't sell Diet Pepsi, so I'm bringing my own or no one will want to deal with me later on in the day!
