Hopefully I can do this but I bought myw tics through disney website 5 day hopper for three. 2 adults and 1 child so my question is can i upgrade before i use them to the annual pass and also how much do they cost i spent 750 already for the passes.
Usual practice of Disney has been to allow you to turn in passes for credit which is then allowed as a deduction for buying AP (even if using a discount for the AP). In your case you would get credit for the ticket cost if nothing has been used but you do not get credit for any portion that was sales tax.
