Mary Jo - thanks for looking into this.
So here's my situation. We are looking at being in DL for May 16th to the 24th. We are considering upgrading to AP's on our last day, however, being that our last weekend is Memorial Day Weekend, all but the most expensive AP's are blocked out. And I am not sure if it will be worth it for us to get the Premium AP's, since we aren't exactly locals!
So here's my question: Assuming we get some sort of combo, would this work?
2 Four day parkhopper passes?

That way, we'd get two MM's, and our full 8 days. Now, here's the kicker - can we use the cost of both of those passes towards our AP upgrade at the end of the trip, or will they only count the most recently activated PH? Perhaps I should just call them - this is getting a little complicated...
Any thoughts from those "in the know"?
