I wonder if they'll make it easy for tourists who typically stay on property to upgrade for 1 or 2 nights out of their 7-21 days. It's something I'd definitely do but as we book through travel agents, you book the whole package.
This is the reason why I'm expecting somesort of package bundle (not using deal this time as it can imply a discount). Disney could implement a time window, similar to restaurants and fastpasses, where only people who are booking a multinight stay can book at this experience. Everyone who's wanting to stay at the SW hotel without a WDW visit gets to book the remaining cabins, if there's any left.
