Just a word of advice, as we did this once. Make sure you go to Guest Relations at the theme parks or Downtown Disney, do not go to the ticket desk at the resort or anywhere else.
1. The resort ticket desk just isn't good at doing this upgrade and have trouble calculating the cost difference (Our resort was 120 higher for each annual pass upgrade)! Also, make sure you get your temporary annual pass (it will look like a normal card ticket but will have 'pass holder' on the bottom banner on the front of the card. This will be your discount card until you get your actual discount card in the mail later down the line.
2. Its already been stated but MAKE SURE that you have at least 1 day remaining on your tickets before you upgrade or you will loose the credit of what you paid for your current park tickets.
3. Once you use your last day your ticket package is considered closed to disney and adding ANYTHING will be at full ticket price.
4. I have seen people do this so many times where they try to add another single day after using their last day ticket and they are shocked to learn they have to pay full price since they used their last day and no longer have an 'active' multi day package to add to.
1. The resorts cannot do upgrades to Annual Passes.
Resort computers don't have the same access to certain files that park and DTD ticket booths and Guest Relations do.
APs must be handled by the ticket booths and Guest Relations at the parks, TTC, or DTD.
2. That's not quite true.
3. Sorry, that's not true.
4. I'm not sure what you might have seen, but guests CAN, for sure, upgrade "all used up" tickets. (Otherwise, guests who just bought a one-day ticket, went to a park that day and decided that they wanted to extend their WDW trip could not upgrade their tickets.)
Here's the scoop.
If you ARE a WDW Resort guest, you CAN upgrade a ticket that has been fully used up, as long as you are still at WDW (have not gone home) and as long as it is within 14 days of that tickets' first use.
If you are NOT a WDW Resort guest, you CAN upgrade a ticket that has been fully used up, as long as it is no later than ON the SAME DAY that you used that ticket's last asset.
(And, even the off-site rule above MIGHT now be relaxed if you have a MyDisneyExperience account with your name and address associated with your ticket.)
The rules about upgrading (or not) used-up tickets were enacted not to stop guests from
extending their WDW tickets after they used the last day, but to curtail unscrupulous and unlawful "ticket resellers" from buying expired tickets from guests as the guests left WDW for home.
Then, the "ticket resellers" would add days to the tickets and sell them to other guests at a profit.
