I don't know anything about
FL Tours but we have used Happy Limo a few times and HIGHLY recommend their service. We had one minor (and I mean MINOR) issue with one of their drivers and they made it up to us by upgrading us to a stretch limo for our next trip at Town Car pricing!
(Just so you know, the driver was out of uniform and holding a handmade sign, he was very friendly if a little, ummmmm, uncouth? He was fired by Happy Limo right after our trip, apprently he had a habit of being late and having to handmake signs, etc. Happy Limo guarantees that you will be met by a uniformed driver carrying a printed sign.) This was our only problem and I did not consider it to be a big deal at all.
