If you book with a good travel agent, they will update your package with the best discounts as they become available. We use DestinationsInFlorida.com for all our Disney travel.January is typically a slow month, so you probably aren t at much risk of losing out, although any deals or promotions Disney has will book quickly, so if you want the best deal, I would book with a good travel agent, now and then make sure they update your package with the new discounts when they become available. Disney has a very forgiving cancellation policy, so you should be OK.That is one of the best times of the year to visit Disney World -- least crowded, good weather, and lowest rates.
Value season rates start Jan 3 and continue all through Jan except for Jan 15-17 since is federal holiday weekend.They are also running a pay for 4 stay for 7 (pay for 5 stay for 7 at the value resorts) special on packages.
