We have been sailing on various cruise lines the last five years in an attempt to discover a favorite. We have not completed our "experiment" but believe we have found it. Our voyage on the Seven Seas Mariner exceeded our expectations by a wide margin. I'm definitely not a cheerleader personality but it's difficult not to be enthused about our recent experience.
We have sailed on other Premium and (so-called) "Six Star" Luxury lines with excellent service, but the level provided on this voyage was above all that we had experienced in the past. All requests were performed immediately, competently, and with a smile. An example: I dropped my laptop and needed some super glue to repair a crack in the case. Not finding any in the sundry shop, I took a chance and stopped by the front desk to see whether they had any. They did not, but said they would check and get back to me ... by the time I walked back to our cabin, the carpenter was waiting by the door with the glue.
I'm not a bar-fly but did enjoy aperitifs before dinner at the various cocktail venues. By mid-voyage each knew my special preference in preparation. Dining service at all venues was equally excellent. What I find nice is that this service is all rendered with no expectation of gratuities.
