Do you want it to be a package? You can make anything a package if you want to. You can do a ticketless package with a dining plan or a package with one day tickets and no dining plan.
The way you phrased the first question I thought you were trying to avoid it becoming a package. Be aware that if you change from room only to a package your one night charge will be refunded and a new $200 (I think) will be placed for the package.
I don't think packages get sold with one day tickets. I feel like someone was having issues doing that last year and they ended up just booking room only and buying the one day ticket separately.
ETA: I can't remember how many nights they were staying...
