Their two edges are very close to eachother in the back. It is a super long walk, though. I rode a bike to the far edge of CBR (past the Pirate rooms) and was surprised to see the back edge of the 50's pool right there.
Yep, they are very close to each other...but, I would imagine that you run the risk of running into some critter encounters!!! And that's nothing I want to do in central Florida!!!
