Weird question about adding days to pass???

[crzy4mk]

I recently won a trip to WDW through my company (YAY!). Included with the trip is a 2-day park hopper pass which they are setting up for us on MDE about 30 days prior to the trip. I am extending my stay and need to add 4 days to the pass. I know this can be done at Guest Services or at my resort once I arrive but I'm wondering about adding the days as soon as I have access to the pass on MDE? I'd like to be able to do this ahead of time so I can book my FP+ for all my days but not sure if this is possible.

Anyone have any experience with doing this? Thanks!

Days can only be added in person.

Depending on the type of ticket, it may not be able to be upgraded at all. If your company was giving away complimentary tickets, those cannot be upgraded. Might not be the case, but just thought I'd warn you.
