Regal had nothing but problems trying to redeem these tickets. They say the problem is on Groupon's side of things. The Groupon is for 2 tickets, but there was only one barcode, and there's supposed to be 2. It even says that in the Groupon, yet only one barcode is provided. Frustrating. Costco sells tickets too, so next time I'll choose that option.
We went here with our kids, and they thoroughly enjoyed this place. There were a lot of things to see, as well as plenty of hands-on activities that were engaging to them. I thought it was a little pricey for the experience, but that's just me. Having 3 kids all under the age of 10 (5, 7, 10) and spending $40 per kid and $50 per adult for admission was a bit much that we don't plan on coming back for a revisit. We made sure to experience all we could on this trip.
