We were on the June 6th sailing and it was fabulous!!!

Absolutely loved the Spirit and would enjoy another sailing on her in the future.
Would like to echo some of the other comments: we saw so many whales from the ship!!! It was magical. However, we did a third party whale watching tour in Juneau on a much smaller boat than the vessel that the Carnival excursion offered, so we were able to view orcas and humpbacks at a much closer distance. Absolutely worth it for us, especially since that excursion saved us money over Carnival's.
Really, the only negative thing that happened was that 7 out of 10 of us ended up sick. My daughter and I had remarked upon the huge number of people who were coughing aboard the ship. Despite lots of hand washing and sanitizing we both still ended up with a nasty virus and here I am, a month later, and it's still lingering! I missed Victoria because of it. My husband was simply enchanted by Victoria, so it's a must-do. Oh well - next time 🙂
