Our resort change experience from today for reference:
Had a 5th sleeper option at CBR 7/12-7/18 and went through the ringer over the phone. Combined total of about 175 calls, two that made it through for a total of 4.5 hours, but dropped. Last call started with a CM, and I was forwarded to guest relations. After a 3.5 hour wait, the GR rep couldn't have been kinder/more gracious. The first thing she did was explain "rate protection" and immediately said we'd be receiving an upgrade to CR with a Lake View room. She even went as far as to repeat multiple times that our original purchase price at CBR would be upheld and read off the deposit we had already placed and the remaining balance. While a total of 8 hours on the phone was wildly frustrating at times (and I about lost my mind at the 473rd playing of "It's a Small World"), the payoff is totally worth it, at least in our estimation. Be sure to let the CM's you talk to know they're appreciated!
Thanks to all in this forum for sharing information throughout the day!
Best of luck to everyone still on the horn!
