The kids and I just returned from some dinosaur fun in Novi this afternoon. The center was easy to find and get to. Beware, they charged $5 for parking. We attended the event within the first few hours of it being open and it wasn't busy at all.
It was dark (although pretty lights were shining on some of the dinosaurs), and with the dinosaurs looking, moving, and sounding real, my kids were quite frightened and very clingy to Mommy. If they didn't like the dinosaurs, I at least did.
Once you leave the exhibit area, you will find many fun activities, but most are at an extra cost, starting at $6. Don't let the signs mislead you. They say 3 tickets for a certain activity, but then you find out that each ticket costs $2. If you are willing and able to dish out the extra cash, your kids can enjoy bounce houses, face painting, a hunt for gems, and even ride a dinosaur. However, my kids were content with the free preschool fun stuff that included coloring, digging for dinos, playing in the dino den (climbing on mini dinos), and watching the dinosaur movie.
I definitely think this was a fun day, and although it was on the pricey side, so are other museums, amusements parks, etc. Gosh, just look at how much it costs to take the family to the movies these days. DiscovertheDinosaurs.com is something special to see and something like this doesn't come around too often.
