We arrived early for the May 23rd Cruise and used Getyourguide.com app to book the Golden Circle Tour 8 hours. Cost a lot less than the Viking offering. $158.94 for 2 people. Nice modern a/c coach and guide.
Say hi to him from (he called me) Mr. Raymond cabin 8000. Always helpful e.g. bringing champagne flutes and opening the free bottle from our cabin fridge and more...
Have a great trip despite the disappointment of the canceled ports.
I was on the May 23rd Iceland to NYC cruise. Two Greenland pilots boarded the ship in Isafjordur and were "stuck" on the vessel until Halifax. I hope you have better luck than we did. Alex and Danielle in the Explorer Lounge are the best!
