I don't know what sort of people go there but I know someone who goes to the KMR program every year. (a relative runs it so they go partly to help out) Its Non gebrocts, chalav yisrael etc but I know nothing about the crowd. My relative who goes its not a fancy person at all though. They have been doing it a number of years and their website looks great.
its in nevada this year.
They're very expensive. They do a top notch job. It's not a robes/snood crowd.
