Using partial-day convention tickets at Universal?

[embracejg]

I was thinking of buying a partial-day convention ticket for Universal Orlando rather than spring for a full-day ticket for a visit later this month since I'll be arriving in Orlando after 2pm anyway. Does Universal actually require you to bring your convention badge to make use of these tickets, as it states in their fine print? I've bought Disney convention tickets in the past and I've never had to do that, so I'm wondering whether that fine print is actually enforced.
