We went for the first time and really enjoyed ourselves! Family fun and as long as my kids are happy, I'm happy.
I think a lot of people that complain about the price have Legoland in mind. This is a Legoland Discovery Center, not Legoland. I came with an open mind after reading all of the reviews and had a great time with my kids.
The rides are cute and super fun as was the movie. A lot of play areas to build with different themes. Both my kids love legos though, so I would say to parents that if your kid(s) don't love legos this will be a waste of time. It is expensive but like I said, both my kids love legos so it was well worth it.
One quick suggestion, less lego displays and more creative play areas! So much space is taken up with those display tables. How about alternating them so we can see something different each time we visit?:)
