Yes, parlayed 28 points into 2 nights in a Grand Villa and 1 Night in a 2 Bedroom Concierge Suite in the Beach Club Resort (not the villas).
We had 6 nights booked in a 1 Bedroom BCV and when we got there the night of arrival our room was saturated in smoke (like 2 pack a day with the windows closed for a week smoke). It was food and wine, so BCV was fully booked, so they moved us to a 2 Bedroom concierge in the resort overlooking the water for a night and then got us in a 1 Bedroom Villa the next day (We missed our diner reservation while dealing with this, so they sent up room service for free, they also gave us a stack of free fast passes for the week that were more than we could use). Then when I logged onto my DVC account after the trip, they had given us the 28 points back on the 1 night we lost in BCV. Those 28 points were borrowed, so rather than dealing with member services to bank them, we booked a studio at HHI for 2 nights a few months later. My parents live in Hilton Head, so we go for a week with the kids every year, that year we decided we would do 2 adult nights at Disney while dumping the grandkids with my parents. My parents dropped us off at Disney HHI and when we went to the desk they said, "Would you mind if we upgrade you to a grand villa". We called the grandparents and they grabbed the kids and the 6 of us spent 2 nights in a 4 bedroom villa. Not expecting that to ever happen again, but Disney Magic does exist.
