You are all correct.

When we were there they told us of their plans to "build a beach." Bulldozers were already in place.

I also looked at the pictures on the website. From my memory, it appears that the furniture in the rooms is not new; the bathrooms might be new; bed linens are definitely new and updated.
Other than the new beach, I see no huge changes to the physical plant.

Windstar used the hotel for their day rooms after the cruise, and because of the nearness to downtown, we decided to stay there before our Marquesas trip.

Hope this helps.
