I've used Execucar with mixed results. They are the business side of Supershuttle. A Honda Odyssey is $72 and the Towncar is $99. On my last trip they tried to substutute a 9 person shuttle for the Honda Odyssey I ordered, but since I had my confirmations on hand they were forced to give me the Honda Odyssey after arguing with the shuttle driver for 5 mins. I personally feel that they tried to pull this as I was a SOLO traveller at the time, and had booked with them direct and not with a TA. That being said, I've reluctantly booked with them again for our family trip in Sept. Hopefully this time things will go smoother than last time. I would recommend that the TA contact them if you are interested, and don't take any flack from them as they can be rude at times, until you get the right person. I've also heard good things about Harold's limo, but have no idea of their prices, and would be best to get a quote off of them before deciding if it's the right fit for you. Hopefully others can make other recommendations in regards to this. And have a great trip!
