Had a 5th sleeper room at PO-Riverside for 8/7 through 8/14. After 2.5 hours, finally got through to a CM. After reading through this entire thread i was ready to ask for the GS transfer immediately, but figured I'd give the very nice CM a shot. While she said she couldn't personally transfer me at no cost, she said that any previously used discounts (fun in the sun, etc) would be automatically applied to your new room, and she'd take a look at my options. Ended up getting a 5th sleeper room at CBR for the same dates for about $150 less overall.
Based on reading the thread, could I have pushed a transfer to GS to see if i could get a better resort? Maybe, but for another 2 hours waiting on the phone, it wasn't worth it as i was more than happy to get an equivalent room, and no need to continue to clog up the phone lines!
