snacks like granola bars, fruit snacks, animal crackers and of course Disney stickers (buy at home park prices are high) to keep the little ones entertained on those long lines. Various sizes of plastic bags and plastic sheets to cover the stroller. Umbrellas. It will rain once a day and sometimes it's a torrential monsoon. Last year I used the garbage bags from our hotel to cover the backpacks and camera bags. Brita filters and packets of crystal light & green tea for that eeeuwww water. I went to CVS for travel size aloe lotion, sunscreen, Glide, anti-itch bug bite spray, Peds, Off packets, cooling wipes and batteries.
