The Grandmaster Han schools are all over in my area. I too am from missouri. I do not mean to be disrespectful, but I am going to be honest. When people on this site begin talking about "McDojos", these are the schools that I think of and make my comments on. You will never be allowed to compete in an open tournament, you must buy everything through your school and it must have the Han's logo on it, you can only compete with other students within the Han system, and you had to sign a really big contract. These schools crop up in my area like starbucks on every corner. You will be a black belt within a few months.
The instructors from these schools go around to our public schools doing demonstrations for the students and when I see them, I am embarassed for them. It's terrible. Maybe it's just these instructors, but they were deemed worthy to teach at these Grandmaster Han schools. Whenever a student becomes a black belt they open up another school and let him teach there. It's like a chain restaraunt and they keep promoting managers, like McDonalds...
I think since each school varies as far as rank and file, it's easy enough for a couple bad seeds to put a negative label on a system - we might not be a "Han's" Youn Wha school but I've met people in the association who have a lot to offer and are really stepped up as far as being knowledgeable and being willing to devote time and effort to further my training. And I'm not a Han-Drone, I've studied different styles over the years and been to the worst of 'em... I wouldn't write off the whole organization/system because of that experience, although I do agree - first impressions are the most important! However our school doesn't seem to operate at all in the fashion that you explained (the ultra-fast promotions/contracts etc) although like I said, I can't speak for every school and it's instructors.
