Can someone explain why to do this? I don't understand why you wouldn't just buy the days you needed first.
I only see a couple of reasons: you don't have the extra money at time of original purchase or you don't know exactly how many days until down there.
Could someone tell me other reasons they do this?
In our case, it's rather simple, we may or may not want to do the water parks (depending on the weather).
So we want the flexibility of adding the WPF&M option after we arrive at WDW.
I've already bought discounted tickets at UT (which were purchased before the recent price increases, so it's almost like a double discount).
If I try to add WPF&M and am
not allowed to get credit for the current gate price, then adding WPF&M will actually cost
more than if we'd just purchased the tickets direct from Disney (because we'll only get credit for what UT paid Disney, which is less than what we paid UT).
I've done the math and know to the penny how much the upgrade should cost, so if I'm told something else, I'll probably do what others have suggested and simply say something like, "I've changed my mind", then, try somewhere else.
(FWIW, as much as I appreciate Cheshire Figment's ticket sticky and believe that it is a terrific and legit source of information, I'm skeptical that waving it in front of a CM will advance the ball much should I encounter difficulty - they're more likely to ask, "is that from an official Disney source?" When I reply, "no, it's off the Disboards", they're likely to respond, "well, you can't believe everything on the Disboards.").
