Your situation sounds a little like mine. My kids attend a dual language curriculum program in Hebrew, but it is not immersion, so there's a real difference.
Our academics aren't the best in the county, but the school is tiny and willing to try new things and they have their friends and their support system there. So, we continue to work with it, even though there might be better straight academic options elsewhere.
Immersion schools are unusual, I believe, and I think that this is why you didn't get a ton of responses to your post.
