I never did recieve my passes from Momtalk.com, (Correction - I just receieved them into today's mail) but there is another website out there offering them as well, Parent Companion. So, we'll see if they come. The waterparks are in Bloomington or Brooklyn Center.
We thought that one day we would go up to the waterpark by grandma & grandpa's house and have some fun there and then go visit them. The passes are actually good for a year, which is great!
