I didn't read the whole thread, this is probably covered......but just so you know, for tickets that you purchased at a discount, such as Undercover Tourist, use them to enter a park before upgrading. Then go to guest services in the park and upgrade to APs. You will receive face value for the tix. So if your
UT price was $20 less than the Disney price, after using the tix to enter a park, you will be credited with the amount of the Disney price.
