We are ones that carry a backpack every day since we still like to bring a camcorder, camera, sunglasses, baseball cap, etc. We also usually rent lockers to stash a spare pair of shoes per person and coats/jackets as we usually go when its chilly. I really don't care for fanny packs under any other circumstances (my mother wears one;)), but on a 10-day trip when my DH has finally had it with the backpack, I will use one maybe for a couple hours in an evening just to stash 'the essentials'. We got ours at WDW on our first trip, so its not stylish, but at least it fits in.
