They can turn on the deluge of pent up AP demand anytime they choose.
The population growth of Florida is not slowing down and that is the major change of the last couple decades. Many people moving just for the leisure opportunities and theme parks.
So my prediction is after the 50th Disney will take a couple major resorts offline and completely retheme them. Part of the result will be that demand will consistently exceed supply. And that will be the case until the train station is built (inevitability). After which they'll finally need that new Bay Lake resort and more.
In the meantime, as it concerns transportation people have Mears, Uber, rentals.
Just my opinion.
