I wasn't aware you could do this...? Can you apply PH remaining days to the MYW tix, including no expiration and PH options?
WDW previously allowed guests to get credit for an old PHP toward the purchase of a new PHP. Everything I've read indicates they will be doing the same for the new passes.
Rash: I don't know the exact hours. The office is kinda hard to find. Look at one of the posted DD maps when you arrive and it will be much easier to navigate. It's right near the middle of the Marketplace section of DD.
Regarding your pass situation in general, just remember that in trading in your old pass you will only get credit for a pro-rated share of the original purchase price of the pass. Furthermore, if you purchased the ticket from a vendor other than Disney, you will not get credit for the 10-15% markup that the vendor applied (which represents the vendor's profit.) Disney will scan the pass and immediately know the EXACT price at which the ticket was sold when you originally obtained it.
Since ticket prices continue to increase, you're often getting credit for day at an older rate and then exchanging them for a new pass with days priced at a higher rate.
And, if the ticket is a Park Hopper PLUS with any Plus features remaining, you will get ZERO credit for any of the Plus features.
If you know about how much you paid for the old ticket, try to determine how much credit Disney will give you. Then compare the costs of upgrading to the 10-day MYW with the cost of just keeping your existing passes and buying a 7-day MYW. I know that they 10-day MYW tends to be a great deal, so it may still be in your best financial interest to upgrade. But at least spend a few minutes running the numbers before you commit.
Good luck.
