My family and I had a great time. Overall the kids enjoyed themselves and the wife and I bought some cool souvenirs.
We decided to wait until the afternoon to go since we figured it would be busy in the morning. It sounds like others experienced exactly what we assumed. We wait approximately 20 minutes to get in the first tent. From there they have you take a green screen photo which we love doing. Once inside, there was a ton of interactive areas for my kids to enjoy. And boy did they have fun. The stereoscopic theater and the 4-D ride were my favorite.
Once we made it to the souvenir area my wife decided to get all of our green screen photos emailed to us since they came put so great. I also picked up a few early Xmas gifts for myself! :)
I found out they will be in San Diego the same time I am traveling through so I would definitely experience this again.
