Adding day to ticket

[Disney102015]

We got 5 day hoppers but looks like we are getting in earlier than expected on our arrival day and might want to go to the park. Is it possible to add 1 day to the ticket and if so how/where? Thanks!

Yes.
Do so at any ticket booth or Guest Relations.

The cost will be $10 per ticket, plus tax.
