The view issue is probably the main reason I don't plan to do this often. I am doing it in January and hope that the special safaris are worth giving up the guranteed view.
However, for what Disney changes for the rooms there I think it's a rip off not to gurantee me a view so I would never pay cash. (And if I get a pool view I figure this will be my one and only time staying concerige..... I think I am going to be so disappointed, that it won't be worth it again.)
