I ended up going to check out Great River and thought it was a good place. The drive is about 30 minutes for me from Burnsville but's not a terrible commute. I really like that the pool is deep enough where I can stretch out vertically in the water and swish around. My lake where my cabin is at is shallow and the deeper areas would put me in the way of boat traffic. I'm trying to convince my mom go with me on Thursday (April 18th) to the water park since we both have the day off. If anyone else wants to, please feel free to join us.
