We brought ziplock bags and put the candy in our suitcases! We're a family of five, but my husband did not collect candy. We brought home four gallon ziplock bags of candy, and we only stopped at each treat station/trail once.
In response to the question regarding the selection of candy:
The Candy. One other note regarding candy. I had read very different reports about the candy available. Now, we understand that we can go to the store and buy all that stuff, but trick-or-treating in MK was a really fun experience and we're glad we spent our time that way. Our oldest son made a list of all the different kinds of candy we received: milky way, twix, snickers, milk duds, m&ms, smarties, nerds, tootsie rolls, now & later, three musketeers, skittles, baby ruth, heath, whoppers, fruit snacks, starburst, butterfinger, reese's cups, werther's caramel hard candy, lemon heads, nestle crunch, raisins, candy corn, almond joy, tootsie pops, peeps, peanut chews, peanut m&ms, and kit kat. No complaints from our boys!
