First sailing on a Windstar adventure and was not sure what to expect. What was experienced was lots of relaxation with just the right amount of activity if desired. The lack of "stimulation" (which I loved) from big ships was a definite plus for me. If you want clubbing and nightly entertainment this is not the cruise for you.
My sailing had only 224 passengers and it was quite nice to actually get to know most of the folks on the cruise and share both onshore experiences and learn what a small world in which we live.
Sports platform was a major plus as to jump or dive into the middle of the crystal clear Caribbean was magnificent. There were also sailboats, kayaks, waterski boats and snorkel trips for guests when sports platform was open.
While we did get a great price --- it apparently came at a price---- that price being this cabin was next to the tender that was lowered right outside the suite at 7 a.m. every port that we anchored at sea. No noise on the day we stopped in Guadeloupe because we docked at the port and no noise first night as we were at sea and no tender service. While it was an annoyance, I usually didn't have much trouble falling back asleep.
