I got my kids' fanny packs at wal mart. They were about $4.00 and worked great. I used a large safety pin to make the fit better and the adult size packs hold alot more than the kids sizes. We filled theirs with pop tarts, crackers and non-melting candy. It was great, they could snack when they wanted to, even if we were in a line! The best thing we did was to take juice pouches to put in the packs. We had a fridge in our room, so I froze the juice pouches (solid) and packed them as we left in the a.m. then they thawed and were still cold in the afternoon. This worked great!!!
