Castaway Motor Coach Tours
They by far had the BEST pricing around; $805 including tip for ~7-hour shuttle. Jason was very easy to work with. They picked up my OOT guests at the hotel, transported them to the church, then to the reception, then back to the hotel. The feedback I received was that the guests really enjoyed not having to worry about driving. One suggestion, have your hotel put a sign in the lobby alerting the guests to the shuttle.
