I am trying to book a tour with the Doubloon tour to Buck Island and Turtle cove while in ST. Thomas. Bert emailed me back and stated that they do 2 tours a day with Princess called Tour S at 8 and 1? I went on the princess website to book the excursion and I didn't find a tour s. I found an excursion to Buck Island and Turtle cove that leaves at 10:30 and 2. Does anyone know if this is the correct excursion or where I might find out which one is the correct excursion? Thanks to anyone with any input.
