Figmentforever24 sounds like one of the people I envy whenever we go to
MNSSHP! DH and I never do anything more than a Disney Halloween themed shirt, and when I see the gorgeous, elaborate, thought-filled costumes some people make/wear, I get so jealous! However I'm not the creative type so I continue to stare in awe from afar

That said, there are always TONS of people NOT dressed up, and tons in Halloween t-shirts and nothing more (well, pants

). DS's now 12 & 8 have always dressed up but as another pp said, even Oct. is hot and before long they'd be taking pieces of their costumes off. We're going to the 1st party this year (hopefully) and neither son wants to dress up. This is fine with me as it is rumored to be Sept. 1st and I believe it will be MUCH hotter than when we've gone in Oct! So, if you decide not to dress up, you definitely won't stand out and feel weird. Enjoy! MNSSHP is most definitely my favorite thing in all of WDW
