We booked through our rep(thomas cook) , because we believed the hype about dodgy local operators and wanted a proffesional service. the extra money put us on a coach which broke down and was repaired but then had no air con ! The guide spoke only broken english and then repeated everythng very slowly " so the non english speakers would then understand" . The poor french and italian tourists must have been even more disapointed than the english. We were herded around like cattle and taken to the most expensive food stops on the island ( 13 euros for 2 milk shakes). after 12 awfull hous on a coach with no air con on a very hot day the guide actally had the cheek to ASK for a tip for herself and the driver because it is customary to offer a "thank you" after a lovely day ! . Needless to say almost every one left the coach in disgust and without leaving the requested tip.
