Discovery Museum has really improved itself from its former location. I took my kids here today, and decided that getting a membership would be a good idea if I wanted to take them back again. $125 paid and we have unlimited visits for our family for the rest of the year. Given its too hot to play outside in the summer? I'm all in.
I found a lot of the things set up did not hold my 2 yr olds interest long. We did find things to do though. Spent a lot of time in the "jobs" area, and the arts area. My kids also enjoyed the fantasy area with the pirate ship and castle, as well as the water area. I'd say ages 3-11 would enjoy this museum best.
We were entertained for 3 hours until I bribed them away with ice cream and a sincere promise to come back again soon.
