Can I Upgrade to an AP?

[txdznydude]

I just returned from a 7 day stay at WDW, Feb. 7th. I already want to go back! My question is, can I now get an AP and will Disney give me credit for my 7 day length of stay pass? Even if the AP would have to be active from the first day of my previous trip. Please help! I really would like to go back but it may depend on what the outcome of the is.

I believe you only have 7 days from the first day of usage to upgrade to an AP, and it does date retroactively to the first day you used your PH pass.

They don't upgrade LOS passes after the fact. It is, unfortunately, one of those use it or lose it passes.
