Lots of fun, but never, ever go on black friday.
There's so much going on at the Harbor and thousands of people there. We purchased tickets ahead of time, and even still had to wait in line for an hour and a half.
It was very unorganized.
I have a feeling it's just because it was black friday though. I went last year and walked right in with no problem. So don't give up on it yet.
Very neat and lots of fun for the kids.
