We leave in 10 days and we are going shopping tomorrow for needed vacation items. My family consists of me, DH, DS6, and DD4. THe last time we went to DW we had a stroller to hold our items. Since our kids will be 7 and 5 this summer we are not doing a stroller. I will want to have my camera, sunglasses, snacks, and other small items. Should we carry a backpack or get 4 fanny packs and each wear one?
