Super cool attraction!
Amazing views - we went at night, and I would think that is the better time to go. However, they know that, and charge a $10 premium for going at night.
I think its worth it, as they views are spectacular.
My fiance has a small fear of heights, but he felt safe and wasnt scared inside the pod. It is very large (fits 40 people) with seating for about 10 people.
Check living social for some discounts.
I think it basically lets you go at night for the daytime rate.
TIP:
Go to the bathroom before hand, the ride is 30 minutes long.
