We did have a problem with a split stay last November. We started at BCV, and then moved to BWV. We even stopped at the concierge at BWV after checking in and asked them to re-confirm that the ME pickup for us was scheduled correctly.
Not sure if it had to do with our split stay, but ME did not show up at 10:20, and not at 10:50 either. They had to send a special van for us...luckily we made our flight.
This might have been an isolated incident, but in the future I would re-confirm ME has us on the list, and in the right place, the night before we have to leave.
