we have only gone once...we were going to try and "SAVE" a few bucks by choosing mears but, i heard some of the down sides of mears the waiting for other people the cramming as many people on the mears shuttle as possible.
SO we went with Tiffany towncar..and OMG, that was one of the BEST decisions we made we had BRian as our driver..very professional, and on time. with the transportation you get an optional shopping trip stop at a local super market. drops you off and picks you up BOTH times on time (actually early both times)
and on there website there is a 5 dollar discount coupon, so for 75 dollars plus tip you get round trip accomodations and EXCELLENT SERVICE!!
oh and i believe its ressie only..just give them the flight number you are on..
