LGP, welcome to PTO!
Below is a link to information about Twin Rivers. I usually visit twice a week, on Sunday and Monday and stay all day. The COs are pretty nice. I'm not sure what kind of information you're looking for, but feel free to ask whatever questions you have and I'll do my best to answer them.
I have found it to be really kid friendly as well--and I take 4 little guys with us when we go. Visits are Fri, Sat, Sun, and Mon. We only go about once every 4 months--and it has been a good experience every time.
