Hi there, Terri!
Disney generally releases its specials and promotional packages 4-5 months in advance of the eligible travel dates. You'll surely want to follow (and subscribe to) the
Disney Parks Blog, for all of the latest and breaking Parks and travel news.
To use Visa's Disney Dream Dollars for booking a trip, you'll need to first convert your points into a Disney gift card. This can be done easily over the telephone or on the card's Web site; make sure to have your login information available if you choose the online route.
When you have received the card in the mail, you can treat it like any other gift card and use the identifying numbers/codes on the card to book your vacation.
These are Disney dollars and not traditional currency, so you will need to book through Walt Disney World Travel, either
online or at (407) W-DISNEY.
Have a wonderful trip!
See you later, celebrator,
