We went on (I think) Feb 5th and it seemed they had worked out the kinks of the earlier parties. There were no lines for rides, very fast moving lines for candy and we easily got a great spot for the parade just before it started. We loved the party (ages 38,34,6,4.) My kids loved the dance parties and all of the special characters. The characters DID have very long lines.
We left at midnight having met many new to us characters, having ridden tons of rides with no wait, probably 4-5 pounds of chocolate. We saw the parade (great and I usually don't care about parades) and the fireworks (also great.) The kids spent FOREVER at Sebastian's dance party. We had a really good time.
