We have gone to the one in Niagara Falls for the last two years. My kids love it, my wife and I hate it, but go because the kids love it. In no particular order -
The food is overpriced and not particularly good.
The entire swim area is chlorinated based on a pool full of incontinent children. If you have any kind of sensitive skin, you will itch for days afterwards.
The waterslides/waterpark area is included in the room price. There are all sorts of extras that are in your face - the games arcade, the gift shop, the photos of you on the two biggest waterslides, etc. Worse, they are in your kids’ faces, so be prepared to get a lot of Daddy, Mummy, may I have …
There’s something really disturbing about the First Nations theme of the place. It’s all the sanitized, Hollywood, white folks version and it’s really jarring. I see your location is Kamloops, BC. There are a couple of hundred places where you can go to experience First Nations’ culture. This is not remotely one of them, and I found it upsetting that the people on real reserves can’t even get clean drinking water, but someone can make a lot of money with a First Nations waterslide park as long as it doesn’t have anything to do with the reality of First Nations’ peoples.
We bring our own groceries and our own booze. Like I say, it’s not my thing at all, but my kids love it.
