I can only share our experience from 2 years ago, and I am hoping the same holds true for our trip in June. We bought Park Hopper tickets at a discounted price from UT. On the first evening of our trip, we went to Guest Services at MK to upgrade to APs. The CM who we ended up with would only credit us toward the AP for what we actually paid UT for the tickets. (How she was privy to that info? idk.) Hence, no savings from the bridging. We politely declined and hopped over to AK (we were headed there anyway.) We got a very nice CM at AK Guest Services who credited us toward the AP for the current WDW Gate price for our Park Hoppers, which is what I expected. We netted a several hundred dollar savings on the “Discount ticket to AP conversion” which more than paid for out Tables in Wonderland membership. So, my point is, sometimes it depends on the CM. I have heard some people getting credited only for what they paid, some people getting credited for the WDW on line price at the time they purchased the tickets, and some lucky people like us, who got credited for the full current Gate price. I don’t know what we will encounter this June with the new dated tickets, but I am hoping for the best! Not sure if this answers your question?
