Changing tickets in package after final payment

[bunny]

I have a package booked for the end of August and must pay my final deposit by July 14th. Right now I have 7 day MYW tickets. If I decide to upgrade the tickets when I get to Disney, will I get charged a change fee? Also is there any advantage to upgrading in advance? I am thinking about changing to 10 day MYW with plusses and no expiration.

You can do this upon checking in w/ no problems and no extra charges. This is our plan also when we check-in in Oct!

Actually, you can change at anytime during your vacation. I have a 7 day booked, will change to an 8 day if our plane arrives on time and we get to the hotel on time.
