We just did a trip to Anguilla. Took Gb Ferries from the airport. About 273 round trip for the two of us. (Slightly double than the ferry from Marigot). 7 of us going over and we were the only two coming home. Paid the 19.00 pp departure in Anguilla with USD no issues. Went to sunshine shack on Rendevous Bay. Wonderful but pricey day. Taxi was about 30 each way for two.
