we used mears transportation in the past. i arrange and pay for before i leave home and pick up our tickets for the shuttle in the airport when we arrive in florida. can't remember how much now but somewhere around $12-$15 per person roundtrip i think. it was very easy and a comfortable ride. when you are ready to leave sea world, you call a number to have your shuttle return. i believe you had to call 1 hour in advance.
