We have sailed on the Summit, Reflection, Silhouette (x2) and Equinox (x2) prior to this sailing. Based upon our past experience we had a general expectation of the level of service and facilities.
On the minus side. the restaurant staff were generally friendly and accommodating (with the exception of the Oceanview Cafe and Mast Grill cooks who couldn't be bothered). In Luminae, it was rare to get the orders right and it was often difficult to get anyone's attention for such simple things as coffee or water. The food in Luminae was not to the level of prior cruises, and we found ourselves getting better food in Blu. The suite butler was MIA for most of the trip, and when we could find her, it seemed like she wanted to push most duties to the cabin attendant. The ship is clean, but it is pretty tired (peeling paint, furniture and carpet that shows years of wear).
On the plus side, the Captain and the Hotel Director were some of the most visible we have ever encountered. The Michael's Club Concierge was outstanding, and provided service we had never received on previous cruises. We had some excellent meals and service in the Tuscan Grille and Murano.
