White water national center

I’m a guest coming into town for chiefs panthers game. Going to be there a few days. Is the white water national center a good idea for a family of 5, all adults, to go for a few hours? It looks fun online, I’ve never been white water rafting before. Does the center stay open this late into the year? What’s the best way to get out there if we are not renting a car? Would I need a wet suit? Looks like kinda a party atmosphere? Any thing to share would be great!
