We used Wilfred Brooks when we would go from O.to GC, but haven't for the last couple years because we've been renting a car. He used to charge us $25 back and forth, I believe he still has his van. If you're not use to driving there I would recommend a taxi because driving in that area can get pretty crazy also parking can be difficult. If you do decide to drive I would recommend getting there early around 5:30 or 6:00 for parking, plus the restaurants get packed any later.
