I haven't been to the GLSC for at least 10 years and I was impressed. I was a little shocked at first by the admission prices but in the end the price is totally worth it!
I took my niece and nephew here on a Saturday and we had a solid 5 hours of learning and playing. The best thing we did was get there right as they opened so for almost 2 hours the place was pretty empty. People seemed to start showing up around noon. I loved the lego exhibit that they have on the basement floor and we built so many cool things. The kids also loved the area for kids 7 and under. In this area they have the best ball pit! I even wanted to be a part of the fun.
I love that no matter what age you are this place is just so fun and you learn so much and it really caters to everyone. We never really had to wait in any lines since there are so many things to try.
