I used Happy Limo twice - once in 2007 to take us from OKW to Sanford airport for the flight home. We flew into MCO and out of Sanford that trip. That time everything went as well as can be expected so we used them in 2008 for a triple leg - MCO to Universal area; Universal to POR; POR to Sanford. THAT experience was

and I will probably never use them again as a result. There were no life-threatening moments but a series of miscommunications and, IMHO, poor customer service issues that I just still can't believe.
I'm starting the debate, myself, of whether we should use a car service or just rent a car for the few days before the cruise. Anyone else have any recommendations?
