Fanny pack for me.
I use a
Kipling (which I purchased based on recommendations here on the Dis!) and love it. I prefer the fanny pack over a backpack for a couple of big reasons:
*No lower-back sweat from a backpack pressing against my back and preventing air flow
*Accessibility to items in the fanny pack, instead of having to take a backpack partially or completely off in order to grab an item from inside
*I also visit the Universal parks, and a three-pronged fanny pack is allowed on all but three rides there.... prevents me from having to put items in a locker for most rides!
*Even though lockers aren't required for any Disney rides, I still feel like my belongings are more secure when they're in my fanny pack, attached to me, instead of being in a backpack wedged between my feet (or wherever it will fit, LOL!)
