Does anyone know if I purchased 3-day tickets for my family through
undercover tourist in June 2023. Am I able to put value towards the 4 park magic ticket when they are released by calling Disney?
Broadly speaking, any valid, unexpired ticket can be traded toward another ticket. Occasionally there will be exceptions, but there's no reason to think that wouldn't work. You'll have to do it over the phone or in person. If the ticket is visible in your account, and costs less than the 4-park magic ticket, you should just have to pay the difference. If your ticket cost more than a 4-park magic ticket, you won't get a refund of the difference.
Make sure you know what the actual advance-purchase price was for that ticket. The amount you should get is the pre-tax advance-purchase price as of the date you bought it. If you bought it recently, you should be able to find out the price by going to Disney's website and starting to buy the same ticket for the same dates; it should still be the same price.
Remember that Disney will quote you the
pre-tax price for your ticket, and deduct that from the
pre-tax price ($396) for the 4-park ticket, then
add tax to the difference. If you have written down the post-tax price, it will appear that Disney is offering you less than the correct value. Be sure to write down the pre-tax price.
Example: I don't know what dates your ticket is for, but let's pick a random start date for example purposes: August 21, 2023. Disney sells a 3-day ticket starting Aug 21 for $340.03 (pre-tax), final price $362.13. UCT sells the same ticket for $349.22 (final price). Total savings:
$12.91.
If you call Disney to upgrade they should offer you $340.03 for the ticket (pre-tax), which might feel like it's less than you paid UCT, but you're comparing a
pre-tax price to a
post-tax price. Don't worry, it will all work out in the end. That $340.03 is applied toward the pre-tax price of a 4-day magic ticket that costs $396. So you now pay $55.97 plus tax, making it $59.61.
In total, you paid $349.22 for the original ticket, plus $59.61 for the upgrade, making your total out-of-pocket $408.83. However, the post-tax price for the 4-park magic ticket is $421.74, so
you save, in the end... $12.91. So you retained the discount you got originally, even if the numbers are confusing
