We boarded Serenade of the Seas as Platinum members. We have been to Alaska many times, it will be our second cruise to Alaska, and we love it. Boarding was very quick. There was no one to show us to our cabin, but we found it quickly. The cabin was very nice and roomy with a deck. We met our stateroom attendant and he seemed very pleasant with a beautiful smile.
On our first day out I went to the Spa and had a Hot Stone Massage. If you have never had one I would strongly recommend one. It was so fantastic I booked another one for later in the week.
When we arrived at Icy Strait Point my husband took the Zip Line and loved it. It's very high and long so I would recommend it only for those people who don't mind heights.
