Hi Sherri!
There's no real way to know what fantastic offer Disney will offer next!
What I always recommend is to book the Resort & Package you're comfortable with in terms of price and date. That way, if a special offer doesn't become available for your travel dates, you'll still enjoy the great vacation you had planned and budgeted for.
Then, keep an eye on the
Walt Disney World website's 'Special Offers' section often as well as TV commercials and newspaper advertisements. If a new offer comes out and you've already booked your resort and dates, call (407) 939-7675 & mention that you have an existing reservation and would like to switch to the "such & such" offer. The Cast Member will advise you of availability under the offer and can even help you compare to determine what's best for you! The offer may vary by resort level in terms of which properties have availability or which 'free' add-ons such as dining are being offered.
For example, I was once booked at Disney's Port Orleans French Quarter Resort (which is a great choice!) when a 'Buy 4 nights Get 3 nights Free' offer came out. I called in, but that particular offer was sold out at POFQ. We couldn't receive a discount off our existing package price at a moderate resort, HOWEVER we ended up being able to upgrade to a Deluxe Resort under the new offer and our total package price remained almost exactly the same! We were thrilled!
I hope you'll visit again soon with any additional questions you may have.
Wishing you a very Magical time planning your Walt Disney World vacation Sherri!
