we're going on a northern lights cruise in february, not on the marco polo though, and stopping off at various places with some trips ashore booked along the way.
as i wouldn't book or not book a holiday based solely on what people on this site say, i don't think it's a bit strange to ask opinions AFTER you book something. you're just after peoples opinions, doesn't mean you'll take any notice of them, same as if you ask someone at work or in the pub.
when are you going johnbjohn?
