On my Norwegian cruise next June, I noticed that Silversea has changed one of our ports from Trømso to Alta. When I check on My Silversea, I only see "spa" and "restaurant" information for that date, with no "ashore" button. In your experience, how soon are we likely to see excursions posted. (I think that Alta may be a completely new port for Silversea, but I'm not sure.)
