This place is awesome for Rapid City. As a new resident, I wasn't expecting to be able to swim in the middle of winter. Awesome features include the lazy river, hot tub, play area with water slides for kids and big water slides for older kids and adults. The temperature stays in the 80s and is perfect for cold winter day.
A couple of things I noticed in the reviews that I thought I'd address. Many people complained about no lifeguards. This is true with exception of one standing at bottom of main-big slides. While I was initially disappointed in this, as I have very high expectations considering the Great Wolf Lodge in Colorado Springs, I realized it is basically a compromise on price. If you get your tickets with the hotel, they are a measly $9.99 for all day, regardless of age. compare this to the Great Wolf Lodge, where a weekday pass can run upwards to $35 a person to a weekend pass upwards to $100 per person regardless of age. It is very clear when you buy the tickets that you must watch over your kiddos. This isn't a place where you can just let your kiddos go and let someone else watch them. Knowing this as an expectation, I believe some of the reviewers would've 1) not purchased a ticket or 2) had a better experience knowing what to actually expect.
For all that's included in the price, you can't beat it. My kids loved the lazy river and hot tub. We will definitely be back as a family, and I'm considering buying season passes.
