Can you add a day to a pre-purchased package ticket?

We booked our hotel/park ticket package through Costco - ended up being a pretty good deal. We are there for 4 nights and the package was for 3 day park/park tickets. We think 3 days will be enough but does universal allow you to add days to tickets? We won't really know until we are there as we might actually want a low key resort day.

If they do allow this is there any way to find out how much it would cost to add one day?

Yes, u can upgrade ur 3 day to a 4 day and u have until the end of ur 3rd day to do this. So u can literally wait to decide to add the 4rh day, just remember u need to upgrade before u leave the park on ur 3rd day. I literally just asked guest service this same question a few days ago. There are 3 of us in my family and we all got AP but I let my daughter bring a friend and I bought her a 1 day par to park ticket and i thought about upgrading to 2 days and that's exactly what guest service told me.
