FlyingDoctorwu, i mean luxury hotels forum regulars in athens, or same flight from LON/NYC etc
id have no problem sharing transportation, as its no different from commercial/scheduled aviation

although in this case helicopter only 1275 vs 1985
luxury yacht 1375 vs 5500 but different situation

400 / 2.5 = 160
400 / 5 = 80

400 / 3 = 133
400 / 6 = 67

per hour not crazy
vs some city hotels
