We were there last week, and we did the Cinderella dinner at 1900 Park Fare for our first night. It was GREAT! First of all, the Grand Floridian is just gorgeous, so my 6yo twin daughters were just in love with the beautiful hotel from the start. Then, the characters at the dinner were wonderful. You get Cinderella, Prince Charming, and her stepmother and 2 stepsisters. The stepsisters are FABULOUS -- really great interaction.
After dinner we went down to the dock. The water parade was just starting up, and we took a ride on the ferry while the parade was going. The ferry driver stopped the boat while the parade was passing. Not only was the water parade fantastic, but they loved seeing the castle all lit up.
We rode the ferry all the way around the route (GF, Poly, MK, back to GF), then walked around the resort a bit. My daugters wanted to walk on the beach. We then walked back to the dock and watched the fireworks with a wonderful view.
My daughers were in HEAVEN! It was really a magical way to start our trip. Without ever even stepping foot in a park, they were having the time of their lives, and it just built up their anticipation to hit the MK the next morning.
