Hi Julie,
Thanks for stopping by the
Disney Parks Moms Panel with your question. Let me try to help you.
Best rates tend to be available when kids are in school. January for example is the least busy month, however some events, like
Walt Disney World Marathon Weekend, or Martin Luther King Jr. weekend will result in higher rates. Starting late August, and then during September, is another low attendance time, with good rates. Some resorts also have different rates for weekdays and weekends.
Special Offers are available almost all year round. Some offer a discount on the room portion of your stay, or discounted or free Disney Dining Plans. Also, sometimes there are special Florida Resident offers too. Although there's not a published calendar available, the folks at mousesavers.com have been doing an awesome job and published a version that shows all the different rates and seasons.
Hopefully you'll be able to find a nice time to go and enjoy the Resort. See you real soon!
Ricardo.
