We are going to WDW July 12-19 and I usually take my fanny pack. I would like to get some type of sling type bag/pack that goes over your shoulder and leaves you hands free. I don't want it to be really big just big enough for wallet, camera, phone, etc. I don't want to just hang it on my shoulder like a purse, I would like it to go across the body so your hands are free but it won't fall off. I know that sounds confusing . I just wanted to get something different than the old fanny pack. Thanks for any tips!
