This has turned into a general answer, as well as to your specific question...
I had quite a long chat with the room assignment manager yesterday, and had a good discussion about requests. He said that the information you give to the reservations center DOES get through to them, and they run daily reports pulling out keywords from the free-form text field (which apparently can contain as much as you want, so make sure the DRC agent enters exactly what you ask them to). For example they have automated searches which pick up words like "Alligator Bayou", etc.
Online checkin helps too, especially in terms of letting them know arrival times and it speeds up the process at the desk as they have all the necessary info already to hand. About 25% of arriving guests are using this facility at the moment. (The "Corner Room" option is becoming a bit of a headache by the way, as almost everyone is ticking it and they only have so many corner rooms available!).
I did suggest adding AB vs. MB as an online choice, but apparently it's difficult at the moment as the listed options need to be able to apply to
all possible rooms, and Preferred Location rooms can't be requested in MB. Hopefully it will come at some point though.
Faxed requests 3-5 days out are still very welcome, but please make sure you address them to the room assignment team generally, rather than to an individual or to the team manager. Otherwise, if that person happens to be off for a few days, or on holiday, the rest of the team may not go through a 'personally' addressed message to their manager. Try to keep to the point rather than giving your whole life story, so the important information stands out. I guess if you find you've written more than a page, you've probably overdone it for a room location request.
Also please keep to the published fax and phone numbers rather than being tempted to try to contact individuals directly; it may work out fine, but Disney have noticed an upsurge in direct communication which they don't really encourage. I think POR is kinda drawing a bit of attention to itself regarding room requests at the moment, and it seems to be showing up on Disney's corporate radar - which may not necessarily be a good thing in terms of their overall desire to offer a consistent guest experience - so it might be best not to rock the boat.
Oh, and yes, the senior folks at POR have worked out that people are using a pre-prepared template and Googled around and tracked down where it comes from.
