I stopped in briefly at OKW during our last vacation. The slide looks like it will be a lot of fun. However, I thought it looked a little more blob-like than castle-like. There were three lifeguards, two for the slide side and one now monitoring the shallow end. That is probably one too many, IMO.
I have always enjoyed the OKW pool for it's size. I'm happy they added a slide, but I hope there will still be time to swim there when the waters are quiet and unpatroled. Are there slide hours? I did not notice.
