This is basically a wonderful ship, with a few glitches. It was recently bought by Windstar and is due to a major renovation/refit in 2020, so these comments might not apply to later sailings.
This is a small ship with huge cabins. The staff and officers are very competent and caring. Food was somewhat variable, ranging from OK to very good. Prices were affordable considering the size and staffing ratio. (We got a last-minute cruise for $999 each in the lowest cabin category, which was just fine for us.)
The ship was surprisingly stable and quiet, given how small it is.
Embarcation and debarcation were flawless and fast.
Passengers were almost all English-speaker, mostly from the US and Canada. Their ages ran from 30's to 70's. None of them seemed like serious party animals.
There were a few glitches:
A related issue is that this ship would be at a disadvantage in bad weather, such as what one might encounter in their Alaska cruises.
Water was an issue: no hot water for a few hours, and then a couple of days later, no water at all. None of these were major issues.
Linens were a bit tired.
Bar prices were high, though not ridiculously so. We recommend buying wine at the CVS across from the San Juan dock and paying the $15/bottle corkage fee. They don't allow you to carry on hard liquor, although I doubt a few miniatures would cause problems.
The all-inclusive bar-WiFi-laundry package is ridiculously overpriced. Anybody other than a really serious drinker would have a very hard time making it worthwhile.
This ship is not handicapped accessible. Nobody who needs anything more than a cane should be on this ship. It is not suitable for children as there's nothing for them to do (the only child on board was the Captain's daughter, who was a delight.)
The base price ($999 in our case) is a bit misleading, as you must add port taxes, basically-mandatory service charge, and bar bills. Our total came to a bit over $3,000 after all these items, plus air fare to San Juan.
WiFi is slow and not totally reliable. I appreciate that they warn up-front not to expect too much. We got the unlimited plan ($240) which, however, doesn't allow more than one device per cabin to be logged on. Consider one of the individual plans.
Shore excursions were very mixed. Because of their cost and the lack of interest in most of the ports, we only took two of them:
9a. Historic Tastes and Treasures of Fort Napoleon (Les Saintes): well worth the money. We learned a lot about the history of the French Caribbean, and saw a really good little museum at the fort. The tour ended with a tasting of various Caribbean finger-foods and 5 types of rum, which was a good way to end the tour. Our leader, Jean (I believe) was very well informed and fluent in English.
9b: Clear Bottom Kayaking (St Georges,Grenada): eminently forgettable. After paddling a mile to where we should have seen lots of fishes, there were absolutely none to be found ... until one minnow literally landed in our kayak. (I threw it back.) Basically, clear bottom kayaks are no substitute for snorkeling or scuba diving--the view was very poor. The rum punch at the end was pretty awful.
9c: The company wanted entirely too much money for pre- and post-cruise accommodations and transportation. My suggestion is to take a cab (regular cab or Uber) to the Sheraton hotel across the street from the cruise terminal, for a fraction of the cost of what Windstar wanted. The Sheraton was a rather nice, modern, business-class hotel, and not terribly overpriced.
Some people have complained about being pressured to spend additional money. This complaint is basically correct. The evening "shows" were mostly commercials for shore excursions and repeat cruises. I could have done with less of that stuff.
No real "shows" in such a small ship, through the crew put on an evening program that was a lot of fun.
The "swimming pool" was basically a large hot tub with underwater jets to supposedly allow one to swim up-current. Too small to be useful.
The sports platform was open a lot less than promised because the slightest wave action caused it to be closed.
The food was never less than good and sometimes excellent. One common complaint was that red meats tended to be over salted. A couple of their pork roasts were mostly fat.
Finally: YES, we look forward to another Windstar cruise.
Huge cabin. Wonderful steward (Ronni). Linens are a bit tired.
Good excursion; see main review
