Upgrading or extending park tickets

[Disneyluvr]

We bought 3 day one park per day tickets for early June, thinking DH wouldn't get the time off he requested. Well they gave him a few extra days so we wanted to upgrade our tickets to 4 days. Are we able to do that even though they are not park hoppers?

Yes you can. Just visit one of the ticket booths before your last day,many they can help you do that.
