I am from Alesund, one of your ports. And next year I am planning the same trip. If you need some info. on the town and what I would suggest doing, please let me know.
Norway is breathtaingly beatiful, and I am sure your ship will take a cruise from Alesund to Geiranger fjord, which is spectacular.
I would like to hear from you when you get back as to what you thought of the ship etc.
I wish you, bon voyage and hope to hear from you.
