It shouldnt be more than £10 scotty but you will have to haggle first . Definately nowhere near £38 as it is only a 15 minute drive. I'd email sunrise and ask them how much they charge for airport pick up . We always stay at the hilton in sharks bay and Im sure their car is about £12. A lot easier than haggling with the taxi drivers but if you do tell them you are not paying more than a tenner .
