Actually those upgrades were sent out because Disney had overbooked the value resorts during
free dining. Until this past winter, all levels of resorts got the basic
DDP for free with this promotion making it an amazing deal at values. This is why Disney started doing different levels of deals at the different levels of resorts (5/2 at values vs 4/3 at mods & deluxes, QSDP at values vs DDP at mods & deluxes). They're trying to balance how many people book at each level in order to not have to give free upgrades again. This is why I believe the free dining deal that we're all sitting here waiting for will be QSDP at values and DDP at mods & deluxes.
