You would probably get more interest on this on in the "Transportation" forum...
Anyway, a limo service (
FL Tours included) is a great option and in my opinion better than a cab or car rental. Overall, the cost differential versus a cab is not that much, plus you get a better experience and more comfortable ride.
Reverted to a cab during the last trip and totally regretted the decision...I'm trying Happy Limo for our upcoming trip...
