TJTrippe--was that recently, that you disembarked early at SXM?? I wondered whether you can still do that. Years ago, we left a ship in STT, flew to SXM, stayed overnight there and met the ship the next day when it came to SXM. I would not do that now.
We were in a similar situation last year when we took a transatlantic repositioning cruise from Southampton, UK to Barbados but we wanted to get off at SXM for a vacation. We asked the cruise company Cunard who said it wasn't possible. We thought about jumping ship but research online indicated there might be a problem departing SXM because they would have no record of our arrival.
So we ended up in Barbados and spent the night at the airport to catch a REALLy early flight to SXM involving a change on another island. Argh !!!!
