We've been to St. Maarten many times, and really enjoy Orient Beach. The tour we took cost $79/each. It was a trip to Orient Beach with a barbecue lunch. We were very disappointed- we were taken to the westernmost part of the beach, to an area that had not been raked. We had expected clean white sand! The lunch was chicken, ribs, white rice, mashed potatoes, and lettuce. I would not recommend this tour to anyone.
Since there were going to be 30,000 visitors on St. Thomas the day we were there, we decided to take the ferry to St. John, and have a short walking tour.
What a good idea that was! Never been to St. John, so we had a chance to see something new.
