Just a heads up that if you're looking for room only, the 407-WDW-IRUN should not be your only inquiry for lodging! We called for the Wine and Dine and Marathon weekend, and in both cases room only was more expensive than general public/non-discounted rates that you can book online. We got a total $698.70/POP room quote from IRUN, and I checked online as it seemed high per night, in fat it was only $652. for the same nights online with no discount. I'm calling in to see if I can get AAA discount for now, then watching for AP after that. Same issue with Marathon weekend, it costs more to book a room through IRUN than it did to just book a non-discounted room only online. The rep on the phone said "I assure you these are discounted room rates", but when I read exactly what was in front of me online, she just said "Oh, well I thought they were but i guess not".
PLUS they make you give a $200/room deposit and you have to pay in full by 45 days ahead, then there's a penalty for changes after that. If you book online or at 407-W-DISNEY you only have to pay 1 night and you don't pay in full for room only until you check in, and can make changes without penalty.
May be a very different scenario for packages with tickets/dining etc, but for room only, call and use AAA or AP or whatever, or just book non-discounted online, you'll save some $ over IRUN.
