we used happ limo on our last trip. we had 2 seperate pickups, 1 airport and 1 amtrak, and had to use them for a trip to discovery cove and then return trip to the amtrak station. they were on time, cars were clean, drivers were very friendy and very outgoing so as you can tell this is a reccomendation. we are using them again on our next trip.
you will definitly hear many different opinions dealing with the other limo companies and a great many of them will be positive ones. of course there will be negative ones also. i believe that the proces arent really much different between the car services so you will have a bit of a difficult choice to make. but honestly after you read the opinions stated here you cant make a bad decision.
happy limo, golden limo, tiffany towncars, southern elegance are just a few i can remember that i have heard many good things said about all of them.
good luck in making a choice. hope this helped
