We went on a Wed, it was $20 per person and we could skate from 3-midnight. You are able to leave to eat and come back at any time. The skates we rented were better than any other skate rink we have ever been to, no shoe laces to worry about, easy to put on and easy to take off. They had seals you can rent just in case you are a beginner and need a little help.
The kids loved this place. The only thing they didn't like was when they closed for about 15-20 minutes to resurface the ice with the Zamboni. The good part of that is they gather the loose snow and let the kids make snowballs out of it.
The DJ played music all night long, some songs were inappropriate for the little ones who were out skating towards midnight. The view was perfect of the strip. It was cold but they had plenty of heater lamps. They also had fire pits if you were interested in doing smores with the kids.
I have to say that they have the best hot chocolate I've ever tasted. You can get a cup for about $6 or you can get a whole thermos for the fam at $25. There is a bar so if you are looking to get tipsy while on the ice you can.
Oh and while we were there a couple got engaged on the ice....nice!!
