I think we are on the same cruise possibly. The ports are Reykjavik, Akureyri, Seydisfjordur, Belfast, Liverpool, and Cork (Cobh). In Akureyri we are booked with Sage Travel for the Lake Mývatn Classic tour. I can't find anything for Seydisfjordur. Cork is only a 6-hour stop on a Sunday for us, so that one is difficult, too.
