Our first cruise was in June, 2007, 10 days, roundtrip to Alaska leaving from San Francisco, on Dawn Princess. Our daughter had honeymooned to the Carribbean on Disney and wanted us and her in-laws to try cruising. All of us loved it!! Wish I had started cruising earlier. Our 2nd family cruise was to the Mexican Riviera on the Sapphire Princess in June of 2009, leaving from Los Angeles (San Pedro). My hubby and I took a Panama Canal cruise (by ourselves) in October of 2010, on the Island Princess, San Francisco to Fort Lauderdale. Hubby and I took another cruise 10 day cruise to Alaska in September of 2011 on the Sea Princess, once again leaving from San Francisco. (We're less than hour from SF) We loved all of our cruises and all of the ships. Alaska is beautiful and I would cruise there again in a minute!
We visited the same ports on both Alaskan cruises, Juneau, Ketchikan, and Skagway. The scenic cruising on the first cruise was to Tracy Arms, the second was to Glacier Bay. Both are beautiful but Glacier Bay was more scenic and we got close to the glaciers. There was too much ice in the water in Tracy Arms so we only got to see the glacier from a distance.
I'll have to look up what excursions we took. We did most of them on our own, not through the ship. Feel free to ask me any questions. I'm sure you will love Alaska.
