Here is the official announcement from Disney on changes to the dining reservation system:
The Walt Disney World® Resort will release a new reservation booking system for dining, recreation and tour reservations in late October 2008. The new reservation system will replace our current Dining Reservation System and will allow you to book multiple dining reservations for your Clients in one experience, while associating reservations to your Clients’ Walt Disney World Resort room reservations.
In the future, Travel Agents and Guests will be able to make dining reservations online at disneytravelagents.com and disneyworld.com with this new reservation booking system. The launch date for this enhancement will be announced at a later date.
As a result of the system upgrade, effective July 29 through late October 2008, Guests will be able to book dining reservations up to Jan. 25, 2009 arrivals. In late October, booking processes will return to normal, allowing Guests to book up to 180 days of arrival.
The system upgrade will not impact Victoria and Albert’s Restaurant, Cinderella’s Royal Table, and Chef Mickey’s Restaurant. Those three venues will continue to observe the normal booking processes throughout the system cutover.
There you have it, as expected, you will soon be able to make all your Disney vacation reservations online in one motion, making the overall experience much easier. Expect the new system to be in order around January 2009.
