The Caribbean - St. Thomas- Cost of taxi from airport to pier

Am looking into taking a cruise which departs from St. Thomas. If memory serves me, the airport is relatively close to the pier.

We'll be booking air separately... the cruise line charges $64 each way (total for 2), but I have to imagine a taxi is far less.

Anyone have the scoop?

perhaps they'll work for a ballpark idea: St Thomas Taxi Rates (http://www.vinow.com/stthomas/getting_around_stt/taxi_stt/)
