does it cost anything to enter? and when is the best time to go, not as crowded? Thank you

Def late afternoon is slowest times.... But there are also a couple of locations... Ponds and downtown... Will need a membership to work out

It doesn't cost to go in. But to work out you need a membership and you can buy one for yourself or a family. It's pretty cheap. The last crowded times are when it is getting fairly late, like 5 to 7.
