Having been the victim of lost luggage before, we always take a carry-on with at least a couple changes of clothes, pajamas, make-up etc, medicine,valuables and anything else we can cram in. That way at least we're O.K. for a couple days until the luggage catches up. On this trip, because of the remote places we're going, the luggage probably wouldn't catch up at all until Bergen, maybe Tromsoe. Since we're going to be in Reykjavik for a few days, I'm thinking any lost luggage we have would catch up before we leave on the ship. Hopefully, nobody's luggage will get lost at all!! I'm going to do a trial packing today to be sure we aren't overweight. If we are there's still time to go back to the drawing board.
