Do you fax them a request a few days before if you want a specific room? Or should I call now and try to do it? We're going down in mid-Sept., I just want to have my bases covered. Thanks.
You should have it noted on your reservation when you make it. If you didn't, call back and have them add it.
If you want to fax, there's a page of information you should read here on Deb's site. It will answer the who, what, when, how, and why's of room requesting.
