Thank you everyone for your replies! I know it's going to be expensive. I had tried Mears and another car service and it seems they are each around $300 round trip. I was thinking of renting a car but it wasn't allowing me to return the car as early as I would like to because they don't open till 9 am and my flight leaves at 7am. I also don't know the area that well and wasn't keen on driving to the airport at 3:30 in the morning. I believe it takes about and hour to get there?
