Caretaker,
This is a matter of poor communication. Had the host explained the reason, be it a safety issue or otherwise, we would have understood. But we paid a goodly sum for that tour, and some traveled from as far away as NH and IN for the tour. This was simply wrong on their part.

I understand your explanation, Dick. My beef with WDW is the failure to communicate. It is unacceptable. Anyway, I'll stop beating this horse....
