I have bridged tickets in the past, but I do know there were some changes relatively recently, so I'm hoping someone can correct me. I'd really like to know this as well.
The example prices are totally made up, just to illustrate the idea...
This is an example of how it worked the last time I did this:
1) Buy a 5 day ticket from
Undercover Tourist (or other authorized discount seller) for $300.
2) Go to the park, use at least one day, but not all of them, go to Guest Services and ask to upgrade to AP.
3) GS will 'credit' you with the current price of a 5 day ticket, say $350, then charge you the difference to buy an AP. So if the AP currently costs $800, they would charge you $450, not $500. And, in essence, you just got $50 off an AP.
I *think* with the recent changes it now works like this:
1) Buy a 5 day ticket from Undercover Tourist (or other authorized discount seller) for $300.
2) Go to the park, use a day or not (it no longer matters), go to Guest Services and ask to upgrade to AP.
3) GS will 'credit' you with the price you paid, $300, then charge you the difference to buy an AP. So if the AP currently costs $800, they would charge you $500. So, even with bridging you still pay regular price for your AP. I guess the advantage is you don't have to pay it all at once, the disadvantage is the AP prices could increase on you.
Is that how other folks understand it?
