Program question?? Please help!

My grandfather has cancer and is currently in the hospital because of a recation to medication. THey live in Florida and I am scared that my step grandma will talk my grandpa into not coming up for the wedding. He really wanted to come up, not only for the wedding, but to see people incase something bad happens in the next few months.

In my programs I have them listed, since they will be walking down the asile, I wanted to print ou the progrmas, but what if they don't come?? Should I wait until the last moments to print and them assemble the programs, or should they be in the program even if they are unable to be there???
