TravelTalkOnline Forums Travel and Vacation Forums US VI and Puerto Rico recommend taxi from airport to ferry St. Thomas!

That's actually about the going rate.

We use Wells, who hangs around Frenchtown and CYOA.
His number is 340-513-2722. He's very reliable.

I doubt you'll do better than $50 for 4 people with him though.

EDIT: Wells costs us somewhere around $10-$15 a head to go from the airport to the CYOA dock. The ferry dock is not all that far from CYOA, and probably roughly equal distance from the airport.
