If you use the ticket once to get in then upgrade to the DVC AP, you will get the full gate price for the 10 day ticket. The price for the 10 day ticket is 237(a) and 202(c) the AP is 369(a) and 314(c) difference is 140.58 with tax (a) and 119.28 with tax(c). See Cheshire Figment thread for info

Upgrading Tickets to Annual Passes
--------------------------------------------------------------------------------
An upgrade to an Annual Pass or Premium Annual Pass follows basically the same rules as any other upgrade of MYW tickets.
Note that any upgrade requires a cash (or cash equivalent) payment and can only be done on a one to one basis. You cannot combine the value of more than one ticket. In other words, if you had a six day base ticket and a one day base, you could not add the value of both to end up with an AP, even with additional payment. If, however, you have three tickets and are paying to upgrade each of them, this can be done on one transaction.
Any upgrade must be done at WDW at a location with access to the Automated Ticketing System (ATS). Basically this is any park (including water park) ticket window or Guest Services location, or one of the Downtown Disney Guest Services locations. The Lobby Concierge staff at the Resorts are not able to handle any AP transactions.
Guests are able to upgrade or modify their MYW tickets any time within 14 days of first use, regardless of whether the No Expiration Option is purchased. After 14 days no ticket modifications or upgrades may take place.
If you purchased your MYW ticket at a price less than the current gate selling price for that ticket (such as from a discounter/broker or Advance Purchase) and you wish to do any upgrade, Disney will not penalize you for the discount provided the ticket has been used. We will make an "intermediate" ticket at the current gate price, charging the difference between your old ticket and the intermediate one to an internal voucher account. Then we will take the intermediate ticket, which is at the current gate price, and upgrade it with the additional days and/or options you want, and you will only be charged for the differences in the current gate price plus tax. Note if you had paid full current gate price for your old ticket the intermediate step is not done.
If you purchased your ticket at less than the current gate price, and your ticket has not been used, you will have to pay the difference between what Disney actually sold the ticket for and the current gate price of the ticket you are upgrading to. It is always best to use one day from the old pass prior to taking it for an upgrade; you will then have locked in the current gate price as the value of the old pass.
If the MYW ticket has been used, the expiration date of the AP will be set to one year from the date of first use of the ticket being upgraded. If the ticket has not been used, the expiration date will be one year from the date of the upgrade.
When upgrading to Annual Pass, if the Guest's original ticket included Water Park Fun & More Option, and any part of that option was used, then the Guest may only upgrade to the Premium Annual Pass. If none of the WPF&M options were used then upgrading may be done to a regular AP.
Okay I read this and let me ask a question. When we use a day on the 10 day ticket and then upgrade it. Do you get credit for the full 10 day ticket or do you only get credit for 9 now since you used one....toward that AP upgrade??? Thanks
