Just got mine on Wednesday and I love it. It seems big enough to hold everything. Even a steno pad in the back pocket and the inside pocket. It will hold a 1 liter water bottle on each side. Not crazy about the flap thing, but will get used to it.
Haven't been to WDW yet, we leave next Friday
so I can't comment on that part. But I really can't see why it won't be great. I have been using it as my purse to get used to it. Won't change back to another purse when I get back though, I'll keep using it.
