How much to upgrade tickets in park?

[2boysnme]

Hi--
I just bought tickets to Universal using our chase rewards points and they came out to 50.00 each for a 1 day both parks.

Is it possible to upgrade these tickets to a 2 day one park each day?
About how much would it cost? Do I get the value I paid or what it would have cost?

I tried calling to ask and they weren't much help.
If anybody has done this and knows please help.
Thanks!

You will get the value of what you paid. The 2 day one park is around $120.
