I've always wanted to like Windmill Island but it is the same now as 20 years ago when I went the first time. Tulip Time is when to go, since the flowers are all in bloom & they have extra programming. The rest of the year is just "meh." The one thing going for it is that they have a real miller who works in the windmill, still grinding grains into flours you can buy on the Island. She trained in the Netherlands, loves what she does, and loves teaching about the mill. If you're interested in that, then it is definitely worth a visit. I think it is worth one visit, but I generally don't go unless they have a free admission day.
