So, Deb's review:

Is almost exactly what happened to us. Head out about 12:30 for 1 p.m. pickup (3:35 p.m. flight). Hubby calls at 1:10, they say "15 minute window, call back", then calls at 1:30, to which they put him on hold to "find his reservation", another 10 minutes goes by they can't "find the driver" or " find his reservation". Finally gave up and flagged a taxi...which rarely is a bargain going back to the airport in this town.
Did I mention that on the way from the airport we got a sponsored Time Share presentation? We decided to go for the amusement value/discounted show, but yeah, just a heads up this company does those presentations on the bus.
These shuttles are fine for going TO the hotel but you end up hosed on the way back.
