How is that ever going to scale. Sure you can try and many do get away with the plane, baggage claim, taxi, ferry?, immigration, then taxi again dance. Why would you plan well in advance for that BS?

To me that is the same Russian Roulette planing as traveling in two different airlines with two different tickets. Just because someone thought they had found a deal. Yes, you can save a few bucks on a holiday that costs thousands. KaBoom one hiccup and you are trying to glue Humpty Dumpty together again with little help from the other parties.

Good luck with your BVI plans and the plans of your traveling partners when you BVI bag does not show up at STT baggage claim.
