I came here with my two oldest kids (ages 5 and 7) and left the little one at home. The older ones are huge fans of the PBS show Cyberchase and were very excited to see the Cyberchase exhibit at this museum. Since my husband had some business to attend to in Houston, we decided to tag along.
We arrived just before the museum opened and, even on a weekday during the school year, there was already a large crowd gathered around the doors. We waited in line for about 10 minutes - and there was no separate line for members vs. general admission (We have reciprocal membership privileges through the Ft. Worth Museum of Science and History). Just as we were approaching the desk, a girl walked up and opened a separate member line. It felt a wee bit disorganized...
As we entered the museum, we found it to be a bit difficult to get downstairs to the exhibit. The main walkway is very narrow and other exhibits are positioned off to the sides - once you get a few people in an exhibit - especially with strollers - it gets very crowded and difficult to pass through. Also, there is only one elevator/set of stairs and they are at the far end of the building - expect to bob and weave your way through.
Once we got down to the exhibit, it was really a lot of fun! There are several Cyberchase-themed games (most of them featured on the show) and a huge replica of the Grim Reeker for the kids to play around in. We went ONLY for this exhibit and spent about 2 hours just hanging out, playing games and playing in the Grim Reeker.
It was fun to come and see this particular exhibit. I can't speak for most of the rest of the museum, but this one was really well done. I'd come back and take the kids to do this again.
