Ziploc bags came in so handy last week. Ibrought the sandwich size and also the large size. Everything in my fanny pack was in small bags --1 ffor money, 1 for license and resort/hopper cards, 1 for gum and tissues.
Then we carried big ones and when we went on water rides camera in one and camcorder in the other.
I also used them to pack kids clothes and labeled each with day of the week. Each morning kids got dressed quickly without messing up all other days clothes!
