Thanks for the tips about the water. My family are also water drinkers. So CS water or bottled. We are also bringing a soft backpack cooler for our lunch. Does anyone take a rolling backpack into the parks? Have you ever seen anyone sitting on a stool or using a backpack chair in the lines? I really appreciate all the input and tips, including having something soft you can multiuse and sit on. I also recently saw iPhone lanyards that you can wear around your neck and clip into the charging plug of the phone. Thought this might be interesting especially to access WWW phone apps.
