I had sailed on Celebrity Summit to Alaska several years ago and it was excellent. This time, on the aging Solstice, while most of the service was top notch, there were disappointments.
First, our luggage was lost on boarding until the next morning. After a few conversations with guest relations the first night, all initiated by us, not once did they call us back with updates, but sent up kits containing 2 tee shirts, and one toothbrush. (More were sent after another request) The next morning after a personal visit to guest relations, it seems unclaimed bags had been reported the night before as sitting outside another cabin.
One bag was also misplaced on disembarkation. I was fortunate to have spotted it amid thousands of bags a few rows away. Otherwise, help from the staff was minimal.
