Sunday 19th. I also thought it would be less crowded ... We'll see! Last year we just did costumes for the 2 DS's and we wore regular clothes. Many, many people were dressed in costume and it was amazing to look at all the outfits! I was glad though that I didn't because it was a hot night and started pouring at 11:00 pm. We were soaked through before we could get to the monorail and any costume would not have fared well. My DH had gotten his face painted and it rained so hard that all the paint washed off! We're thinking of Halloween t-shirts this year to be "in the spirit" if you will, but still comfortable!
