The Tuesday party of Columbus week was a new addition last year. Previously, they skipped both the Sunday and Tuesday parties in favor of Monday. In 2014, all of the parties that week sold out, but the addition of Tuesday in 2015 helped and none of the weekday parties sold out. Unfortunately, there's really no way to predict what crowd levels will be like, but I expect overall park crowds that week to increase, as they have each year. I would go with the date that fits your schedule the best.
You can wear a princess dress as long as it isn't hitting the ground. The ground rule has always been a rule. I suspect they want your feet shown so they can see if your shoes look like they could be concealing something.
They will all sell out. Just pick whichever fits your schedule best.
Try having full face/hand make up on AND a long dress/long sleeved costume. Even with setting/sealing spray I had to reapply it multiple times and anything i touched it came off on. Not fun when your costumes not even drycleanable....
It was a great night but we burned up, but I refused to take off our themed hoodies as they made the costumes, with the horns on the hoods. Thought I was going to have a heat stroke though. I had a blast dancing at the dance party with Sulley, he loved my costume and spent a whole song dancing with just me haha!
