We went during the daytime and it was $25 per person. Not the cheapest experience for sure but it was well worth it. We were in a cabin with only one other family (of 3) so the 5 of us had plenty of space to spread out and to take as many photos as we wanted.
The guide video was sarcastic and funny; it might not be everyone's cup of tea. The view from the top was incredible! I've been to plenty of observation towers and ferris wheels and this experience did not disappoint.
They also have a Happy Half Hour option with open bar if you're interested in drinking.
