In my KI experience, every move done "IN a season" has a big reason. I don't believe the "shade" tagline. If they've moved, they've moved for a higher reason.
I do, for they spent some money to shade the pool, my guess is they wanted to see if they were going to make any money off of it first. They may have gotten a lot of complaints about the bubbles getting to hot in the sun? Either way, I am not convinced the new ride will go in it's spot, but I could be wrong, yet again!
