I hope that we find out what the rules are well before the parties start. We are going to cancel our October WDW trip and go somewhere else if there are no adult costumes at MNSSP. Our favorite part of our fall WDW trip is going to MNSSHP party (we go 2 or 3 times during our trip week) and seeing what all the adults are wearing. That is what makes the party and sets the atmosphere, especially since they cut out some of the character meets and one of the dance parties last year. Last I heard was the thought was that they were going to allow adult costumes, but that there were going to be tighter rules for them such as capes can not go below the waist (so much for my full cape Cruella costume), no robes or layered costumes (so much for Jedis or Darth Vaders), nothing that touches the ground (so much for long princess dresses), no box or prop costumes around the body (so much for UP houses, push the talking trash can etc) and some other things. I'm not thrilled with those restrictions as we have seen some fantastic costumes at MNSSHP that would be prohibited under the new rules if those are what is implemented, but it is better than nothing. We've had 3 FP+ trips and really don't care for FP+ at all. We love WDW and have ignored the naysayers and complainers regarding cutbacks and other bad changes (other than as refers to FP+ where we wholeheartedly agree with all the complainers), but on our trip last October we really felt for the first time that there were so many little cuts here and there that it really could be felt and that we were paying more, but getting less. I think no adult costumes at MNSSHP would be enough of a cut to be a deal breaker for this year's trip.
