I had a bad experience with Dolphin as well. We were departing from Scrub and they took us to West End and put us in a cab to Trellis Bay and put us in the free Scrub ferry. They were supposed to take us to Scrub...not put us in a cab across all of Tortola. They did the same thing to us on the return trip. They claimed bad weather and wouldn't provide any price discount or rebate. The seas looked very reasonable. The owner claimed it was a lot worse near Scrub. Really poor service. Alternatively, I had a great experience with Chillout Charters. I highly recommend them.
