DH and I used Mears for our Sea World day, last year. It cost $12 pp, r/t, then. Like Princess Tink said, we called them, using the direct line phone in the ASMu lobby, the day before we wanted to go. They picked us up outside the lobby. We did have to stop at ASMo to pick others up, but that was it. When we wanted to come home, we called about an hour before, they were there, within 15 minutes or so, for the return trip. I would definitely use them again for this.
