www redirect for subsites in folders

I have a multisite site - http://www.rainbowstation.org. All of the subsites are in folders. If someone types in rainbowstation.org/wyndham for example, they get redirected to http://www.rainbowstation.org. I'm trying to redirect to http://www.rainbowstation.org/wyndham instead. Tried a few .htaccess items I found, but nothing worked. Have a redirect plugin also and set them up in that, but that didn't work. Any ideas?
