I'm very lucky because both my DDs are willing to wear fanny packs and help carry the load. We have one hair brush (small), one deoderant for the girls and one for DH, sunscreen (small), Small wallet, advil, plastic bags to put the fanny packs in on the water rides or if it rains, cell phone, wet wipes, hand sanitizer (small), my glass case (I have one pair of sunglasses and one regular for inside), pennies and quarters for pressed pennies (the bags get lighter as the day goes on), and touring plans (laminated of course). I might be forgetting something but you get the idea.
Everything is as small as possible. I know that may cost more, but I like the convenience. We have extra ones at the hotel if we run out.
DH carries his wallet attached with a chain (his wallet was lost/stolen one time at EPCOT), cell phone, and camera (on his belt)
We start the day with one water bottle each and then either refill or buy as we go. We don't mind carrying them.
We do not carry rain gear. We just get wet or find a place inside. We have been extrememly lucky with this. We also don't do the autograph thing, just pictures.
The best present DH gave us last year was that he offered to carry his backpack with everything in it on the last day so we didn't have to wear our fanny packs.
I was a little worried about having all the items in one bag but it worked out great.
I love the way Disney has places for your belongings on the rides as opposed to leaving it behind on the platform like Hershey Park.
Of course, if I had a baby none of this would apply.
Have Fun
