We have used both Tiffany Town Cars & Florida Tours during split stays. Both companies confirmed the different resort for pick up as we were dropped off. I think they deal with this pretty often.
Tiffany was the first service I used but I switched & used Florida Tours for several years because I wanted to support a DisBoards sponsor. But last Sept Florida Tours was about $27 more than Tiffany due to their "fuel surcharge". (Remember gas prices were back down at that time.) I was unhappy with that surcharge & used Tiffany for the first time in about 5 years.
We were very happy with Tiffany's service! The driver was actually
waiting as we descended the stairs at the airport. The last few times we used FL Tours, we had to stand around & wait or search to find our drivers, who were late to arrive. We actually had time to collect all our luggage & still had to wait for the driver in 2010 (FL Tours). On our return trip (with Tiffany), the driver was not only early, but again waiting, holding a sign with our name. No guessing if that was our car.
We are headed back in May. While I haven't checked prices yet, I'm pretty sure I'll be booking Tiffany again. Have a great vacation!
