I wonder if the info from the bracelets and other swipes shows that the sweet spot for a stay (max $/person/day) is around 4 days and after that the money is just spread out over the longer stay so they want to get you in, suck up your cash, and get you out to move another vacationer in. Gotta believe they see some trend like that.
Thats fine if they are at max capacity. But how often are they hitting that?
