Airport to Westwind II
The taxi rates are set by the government. The taxis are metered but some runs are flat rate.
The published fare for the airport to cable beach trip is $15. BUT, this rate is for two people. Add $3 per person for extra people and there are also extra charges for more luggage or large suitcases.
We were charged $30 for four adults, five pieces of luggage and a wheelchair.
I think the driver charged $30 and included his tip in the amount. I tipped him on top of that, but it won't happen again. Ask if the amount they tell you includes a gratuity.
Here's another hint, If you use a porter to bring your luggage from the carousel to the street, he'll take you around the line and you won't have to wait in the line for a taxi. You will have to tip him, though.
