We just returned home, and I am up to my eyeballs in laundry, even though I managed to wash a few loads at OKW during the week. I thought I should post my experience with ticket upgrades as soon as posssible in the hopes it helps someone else. We arrived Saturday(5/31), and I immediately went to the Guest Relations booth at the International Gateway entrance to Epcot to upgrade our 6 AP's to Premium AP's. The male castmember informed me that I could only get a "credit" of what was left on the passes, and could apply that to a new PAP. In the case of my 2 children's passes, it would cost @ $300 each to upgrade, and even more for the adults! The castmember did not even mention the waterpark/DQ AP for $131 for DC members that would have been good for 1 year...he insisted there was nothing else to do since I purchased the AP's more than 7 days prior. The next day, on my way into MK, I decided to go ahead and upgrade a 5-day hopper plus with 4 options I had purchased in March for my husband at Wal-Mart for $256. I was only credited $222 towards the PAP, even though the pass had never been used, and I had the receipt to prove what I had paid. The upgrade had been done before I realized I was losing $34, so I just paid for it. I was also quoted a price to upgrade my older daughter's adult AP to a PAP that seemed to match what I had been told over the phone and on this board. However, when the castmember checked with her supervisor, she came back and apologized for misquoting the price. It seems AP upgrades are not pro-rated at all. Instead, I paid the full $122.50 cost difference between the AP and PAP, even though I kept the same expiration date in October. Again, the castmember did not suggest I purchase the waterpark/DQ AP for $131 that would have been good for 1 year. Luckily, I had printed the ticket info from Deb Wills' site before leaving, so I could consider all options. In the end, I paid the $122.50 for the upgrade instead of the $131 for a separate pass for the waterparks and DQ for the convenience of having to keep up with 6 passes instead of 11. I am not posting this to start a debate or complain, I just wanted everyone to be aware that what Disney is actually doing is contrary to what we are being told, and it put a slight dent in my budget. Everyone here is so kind to share info, and I thought this would be good info for someone planning to upgrade from an Annual Pass to a Premium Annual.
