I completely understand your reasoning. Back when we had a stroller, I've never been more miserable than the time we closed down MK, walked onto the ferry, then hit a wall of fatigue that I never knew existed. Also, time stands still when they are loading that thing. This was our first, and last, day trip. I didn't think I would survive the 2 hour drive home, and vowed never to do it again. This is why we bought
DVC. I am ok though with a boat ride back to WL, it's my favorite resort. I am also a fan of split stays, we're doing one in a few weeks, so I definitely want to own a MK area resort, just haven't decided which one.
As for the fireworks, while we do love them, we've seen them so much that it's not that big of a deal for us. More often than not we head out of MK when it's starting to get ahead of the crowds, or if we're camping at FW we go to the beach to watch.
