Our Room Finder tool starts sending room requests to Walt Disney World room assigners starting 30 days prior to check-in. If you add your Room Request later than that, we will try to send the request the next morning.
In the past (prior to August 2019), we sent room requests to Disney hotels via fax machine starting just 5 days prior to check-in. At Disney's request, that practice has stopped in favor of a new process. Now we send requests up to 30 days prior to check-in. Disney receives many room requests each day, so we feel it is sensible to get your request in Disney's hands as early as possible. If you configure your Room Request (via the Room Finder or on your trip dashboard) as early as you can, we will take care of that for you!
