I'm going to go out on a limb and make a prediction (something which I rarely do).... That Disney will make some minor changes to this program over the next six months.
Whew! That took a lot out of me.
What kind of changes? Could be anything, really. Some aspects that are more likely than others is the transferability of the deposit -- maybe they'll do something like the cruise lines do, where the deposit becomes fully non-refundable only at 90 days, and is only partially non-refundable before that. Maybe they'll change the specific rules associated with the change fee a little. That seems possible.
