I've only been to
MNSSHP once, and while I currently have no plans to go again, I hope they don't prevent older teens and adults from wearing costumes. I dressed up as Snow White, and it's a silly thing, but it made me happy each time a CM called me "Snow" or "Princess". (I had on a cheap costume store dress-- nothing children could misconstrue as the 'real' Snow White.) I never had the princess-makeover-at-Disney-World experience as a child, so I truly enjoyed the opportunity to gently indulge in it for a day. I was hesitant when I left our room at Pop in my costume, but once we got to MK, I was so happy to be dressed up. My husband and I had so much fun running around collecting candy, me with my Nikes peeking beneath the hem of my Princess skirt. I felt young and light in that moment, and it wouldn't have been the same if I were in plain clothes. I hope trick-or-treating around the Magic Kingdom in costume continues to be open to people of all ages.
