My family went last month. We all love to play with the Legos, so I think we really got a kick out of miniland. There were also these catapult type rides that were lots of fun. However, it definitely was geared towards kids. One section of the park was geared towards pre schoolers, so we took a pass.
There is a section of the park that is loaded with rides where you'll get wet. Come prepared (I didn't) with swim gear or a change of clothes.
We got there around park opening and were there till closing. Other than the pre school area, we did everything. It was a good day. That said, if I didn't promise the kids we'd go, I doubt we would have made the trip. I am glad we did, because we ended up in San Diego the next day and LOVED the zoo.
