It was always my dream to cruise the Tahitian islands and it was my chance to try the Windstar Cruise Line. I was not disappointed in taking this cruise! I have limited experience in cruising, having only been on an Oceania Cruise before this. I think Oceana sets a high bar and this cruise met that bar.
The cabins on the Wind Spirit are all the same size. There is a price difference between level 1 and level 2 and cabins in the mid-ship. I do not see any real difference in these cabins other than a few extra stairs and the water level outside your 2 port holes. I would avoid cabins 205, 207 and 209, which are right by the tinder. The people in the cabins will look out at the tinder but to be honest, can't say when I was on the tinder, that I could see in these cabins.
The cabins had a ton of storage. Sufficient hanging space, 4 drawers and more under the seats of the banquette. Shelves in the bathroom both above the sink area and below. There were shelves next to the bed for night reading and other items. Outlets were US compatible. The TV in the room was adequate. There were a variety of movies that played during the week and a ton of DVDs in the library. We only watched the news when getting ready for the day.
I would not pay more for level 2 cabin, do not see much difference.
