God only knows what the weather will be like. Literally!
And if you click on the large organge button at the top of this page that says cruise reviews you can read all the reviews for RCI (95% good to excellent I would say).
You are probably coming into if not in a period of more unsettled weather at the end of October. I have known temperatures in the 20'Cs as well as heavy anorak weather. Istanbul at this time last year was about 15'C, I was there. So lap of the Gods stuff. There is always loads to to below decks if you can't get up top so don't worry from that angle and if you're really mischievious in heavy seas walk around the cafeteria with a runny fried egg and bacon asking greenish passengers, "Have you ordered this?". Neil ( Not really).
