We got to stay one night. Typical Disney...they are prepared.
There is a concierge all night. You just have to call them to go out if you wanted.
I am a runner and they would have let me run through the park for my morning run. Too tired to do this though!
We won on a night the park was open to 3:00 AM. It was awesome. The Castle Suite is one small part of what you win. A concierge takes you to the front of any line you want...as many times as you want. We got to eat at Cinderella's Royal Table for free. Cinderella actually stopped the line to meet my 7 year old daughter (She was the one who one). Fairy Godmother stopped the show to announce my daughter. We got preferred seating for the night parade and we were in the lead car for the afternoon parade (we rode with Daisy duck). The next morning we got breakfast with Pooh and Friends at Crystal Palace.
Those are just the big things....the details made it even better. (Can you say - Cinderella's Pumpkin Carriage...in Chocolate!)
No taxes, either.
