I love this place. We bring our daughter here for swimming lessons and she absolutely loves it. Its an indoor complex and the H2O is always a heated perfect temp all year round!
We've been to the pool over at the multigenerational center near GVR which claims to be heated and maybe it is heated a little but still really cold when you get in.
Heritage is a little ways from where we will in Henderson but I don't mind driving a little more distance when she enjoys the swimming lessons and does not have to worry about getting hypothermia!
