Thanks Jamie ! Now that is a real travel tip tip. Never considered bragging the shuttle driver. And yes ffto it is a male thing you r right. But apoligizing at the sexy pool over a couple of mudslides with your lady in a skimpy bikini isn't really a hardship.
I am not sure who we used, but it was a White Van outside the airport. We asked how much (4 people 6 suite cases) He said $80, we said no $60 and he jumped on it. We gave him $80 cause he was a great driver, and showed us around the city. Taxi ride back for $60 on the last day.
