In the reception at each Allstars resort is a telephone which links you direct to Mears for free. Buses start running to Universal at 7.05am and return throughout the day to very late. You book a place to go (I went on the 8.05 to arrive in time for park opening at 9am) and then you can either book a return time then or just ring them a couple of hours before you want to be picked up and they'll give you a time. It cost $15 return and the service was excellent. One word of warning, be on time as they don't hang around for people!
