The cabanas are simply a way of sucking more cash out of people with more money then common sense. Let's keep the drama out of it. Just like going to WDW to begin with, no one is holding a gun to anyone's head to force them to go or to rent a ridiculously useless cabana. I can see it starting out as interesting, but, so many factors are going to enter into it that before to long it will be in the same place as the Spectromagic Parade. The climate, the logistics, the cost with no real return will do them in eventually. Some will try it, some will even like it, but, will there be enough. Time will tell, but, I'd like to see the enthusiasm right after the first sideways down-pouring rain comes flashing through the park. Or even if they are still there at that shortly after that.
