Were the Poly-WL and Poly-CR boats a long time ago? I have no memory of them.
(When I was doing editing for the Official Guide a few years ago, they had mention of the Poly-WL boat, and I had it removed - I know it hasn't existed recently, but truth is, I figured it had *never* existed.)
I don't know for sure about at WL>poly boat, but there was definitely a FW>Poly and a CR>Poly boat back in the 70's, probably into the 80's when GF was built.
I took the boat from FW to Poly many times to go swimming. Pool hopping was not frowned upon then. I think some time in the mid 80s they did away with the boat.
I want to say when we were there in 2001 there was a boat that went around to all the resorts (WL, Poly and GF). I think there was a separate boat to MK.
