We've booked a 10-day cruise and are now debating what we plan on taking to and from the boarding dock. Will taking the local bus with a couple of transfers, or a taxi that will take us there in one trip but there's road construction and thus a detour, or a helicopter to fly directly, get us back from the cruise faster? Obviously, taking the helicopter (at least for the return leg) will get us back a bit faster, but we're talking perhaps a couple hours difference at the end of a 10 day cruise! =:^) -- Duncan - List replies preferred.
