We had been on a Viking River Cruise 2 years ago and it was outstanding. We had never been on an Ocean Cruise because we did not like the size of the boats and the crowds and being at sea for very long. We we saw the Viking Ocean Cruises come available - we knew this was a good fit for us. Everything on the Viking Sky was outstanding - Ship services, room, facilities, service, entertainment, food (wow!!). We arrived in at the ship in Barcelona early but we were able to board the ship right away and were in our room by 11am. Then we were free to explore the ship, the city, etc. The shore excursions were all great and the tour guides were very good (we only gave one tour guide a needs improvement rating). Could not have asked for a better experience. Great job Viking - can't wait to go again!!!!
