We were very impressed with the WindSurf. It was clean, the staff was very friendly and the food was excellent. WindStar markets themselves as being "casual elegant" and that is correct. They do not have the European level of service as Seabourn, but you should not expect it.
Service in restaurant was good and the menu between main dining room and bistro gave you ample selections to choose from.
The ship is a great size and fairly stable. When we did have a 55mph headwind, we found ourselves 2-hours behind schedule and were not sure the ship would fit under the bridge going into Lisbon. It was very exciting as they sent a crewman up the mast to advise if we would not clear it - we were close! Had we not fit, they planned to tender everyone to the dock, not a good option for people with lots of luggage or flights close to arrival time.
Embarkation and debarkation was among the best we've experienced. Very organized and fast. Only issue was local customs officials and we all know cruise lines can't control that.
The cabins and bathroom are comfortable and have an amazing amount of storage for the overall SqFt. The bed cover is bad polyester and the bed mattress did have a worn center. Pillows are tiny so if you need support, bring your own.
The fitness room is in a great all-glass room so it is wonderful for your workout. Weight machines as well as free weights, cardio machines and mats are all you need. Towels and chilled water are available, as well as antiseptic wipes for the equipment.
The entertainment tried to do something for everyone, and with such a mixed crowd, somewhat missed everyone. Maybe it was the particular group on this cruise, but most people did not hang around the musical groups. They either went to their cabin or stayed out by the pool bar.
The pools are small, but the two hot tubs on the back of the ship are a great way to relax, yet still be in the thick of the action. But if you are looking to soak and get away from it all, it won't work for you.
As for nit-picking: * The store has very poor quality logo items and overall selection (mostly Tommy Bahamas clothes) * The ship's camera was out of focus the whole trip and the system never gives you ship's data (such as wave height, wind, direction, etc.) like other ships do * The wine stewards do need quite a bit of training. The worst offender just plunked down the wine list and mumbled "Want wine?" as he drifted past the table. * You cannot take your own beer or spirits onboard, but they don't tell you that till you are boarding and they take it from you (returning it at end of the cruise). You can take wine but there is a $10 corkage fee. * When you order a cheese tray via room service, the only crackers you can get are saltines, no variety or no-salt options. But you can pick them up at the lunch buffet.
