Can you add park days to PH ticket?

Does anyone know if you can add park days to your Park Hopper ticket, say if we buy a 2 day PH, and when we are there want to add another day, is that possible? I know you can do it at WDW, but now you have to add it before the last day of your ticket.

Not a problem. You have to pay the difference in price. I have heard there is sometimes an issue if you bought the original ticket at a discount, as they may need to see you the extra day at full price. This means that you lose the original discount. Just FYI. I do not know how this works. When I upgrade my PH to a DAP last summer they gave me full credit for the PH even though I got it at a discount beforehand.
