Really cool experience but probably a bit overpriced. The glass floor is fun, scary, and exciting all at the same time. The view is really awesome but if you are willing to pay a bit more to got up to the Sky Pod you'll get an amazing view of the city!
Best Advice: Go around 5 or 6pm, experience the views during the day. Grab some dinner at one of the restaurants onsite and then check out a the great views at night of all the city lights.
