We've used Mears three times since Oct and recommend them. They're $18.00 round trip. Sometimes we've stopped at another resort and sometimes we've gone directly to Universal. We'll be using them again in Sept and Nov. Their number is: 407-423-5566. If you buy the vouchers at MCO you can use a credit card, but if you wait to pay the driver at pick up you will need exact change. Either way you would need to call the day before you want to go to choose a pick up time. We've never had a problem getting there before opening. The vouchers you get at the airport do not have a specific date on them, so you can use them any day you choose. Gratuity is not included in the $18.00 r/t fee of course.
