I am with Stoop on this one, only used them once, that was enough after standing at the Dalaman with no flight on the notice board and then being told it was cancelled, but don't worry there is another one in four days. We both decided we never wanted that experience again. The guy I felt most sorry for was the young Oil Worker who was due out on the rig the next day to relieve his back to back, he was frantic and was really scared he was going to loose his job.
