If you purchase the tickets from the Universal website, you can do the Kiosk pickup. Basically at both parks they have these computer stations. You bring your confirmation number and the credit card you used to purchase the tickets. Type in the number, slide your credit card, and your tickets print out. No need to visit a ticket window. These normally have no line at all.
Also, as a side note, I have had my theme park ticket on my room key at Universal before. It has been awhile since we did this since we have AP now, but we booked a package and the ticket was right on the room key (just like Disney). Also, Disney is not always like this either. You HAVE to purchase a package at Disney for your theme park ticket to be on your room key. We normally never book a package (because for some odd reason, the price is always more with a package) and have been told over and over again that the theme park ticket can not be placed on the room key if it is not a PACKAGE booking.
So, unless Universal has changed in the past few years, both resort put your theme park ticket on your room key ONLY if you purchase a package deal. For you, I would go with the Kiosk pickup. No idea when they turn the machines off and on, but even if they turn on at 7am, it only takes a minute to get your tickets.
