Disney will occasionally offer promotions and discounts during slow seasons in order to boost attendance and fill resort rooms. There are a few things to know about these promotions to help understand how the discounts work.
Discounts are not “stackable” this means that you cannot get more than one discount, so if Disney is offering a room only or free dining you cannot get both. You will want to compare the discounts in order to figure out which will be a better value for your vacation.
Promotions are generally offered during the slow seasons, this means holidays, spring break and summer are not going to be discounted much, if at all.

Discounts are not guaranteed! There are many, many times when the rooms will sell out, or they don’t apply for your dates of travel, or for the resort you have booked. Room categories or entire resorts will be excluded as well. Travel agents have no way to guarantee a discount or promotion until it is offered from Disney and a deposit is paid on the booking. You will need to act fast in order to secure a discount when it is offered.
So what types of promotions does Disney offer? Room only discounts are fairly common with Disney. The amount varies by resort, Values are usually 15%, with Deluxe Villas up to 35%. Kid sized offers mean that the price of some of the package components will be the same as the children’s price. Extra day of tickets, this is usually a minimum of 4 days with an added 5th day free. Free dining, at Value resorts they offer the quick service dining package for free, and Moderates and Deluxes get the Disney Dining Plan for free. There is usually a minimum amount of nights and days for park tickets that you will need to book in order to qualify for these discounts.

PIN codes are another very common form of discounts that Disney offers. It is unknown how to get on the right mailing list to get these but the best advice I can offer is to make sure you are signed up on the Disney.com website to receive offers and these will at times be sent via email. The catch? If the PIN code is in your name you have to be the lead guest on the reservation.

Bounce back offers, this promotion is probably less well known but can be a very good deal. A bounce back offer is a booking that you will make while at Disney for a future date. The offer changes every so often and must be booked before you leave Walt Disney World. If there is no information in your resort room about the current offer just dial extension 8844 and you will be connected to guest services. Also if you like to use your favorite Disney Travel Planner (ahem) you can just list them with your reservation agent or transfer the booking within 30 days.
Having an Annual Pass to Walt Disney World can also get you a resort discount. Be sure that your AP is still valid and make the reservation in your name.
Disney Visa cardholders are also eligible for discounts on occasion. In the past these have been released prior to the release of general public sales. You must have the Disney Visa card in order to apply these discounts.
Military Discounts are also available for active and retired military personnel with a valid identification card. You can purchase discount tickets at the Shades of Green resort located near the Polynesian Village Resort.
Florida Resident are also offered discounts on tickets and resorts with a valid Florida issued ID.
No matter what discount you are looking at there are always ways to save money on your Walt Disney World vacation, if you take the time to plan it correctly and do a little bit of homework! Of course you can always leave this to a trained professional who can help with the ins and outs of getting the most bang for your buck.
