The swim struggle is real

So we (I) decided to do this work summer party at the local minor league baseball field. They have installed a "lazy river" on the hill behind right field, and you get to go watch a game and have food and drinks (including beer and wine) and then float around if you so choose. The CEO will throw out the first pitch, and I think it will be fun - unless no one wants to get in the water in front of their co-workers. Which I totally get. I really don't, either. So now I'm thinking I will open it up to families because certainly kids will want to do it...I hope??
