Has anyone attended Bhante Vimalaramsi retreats?

The reason I ask is because I've been doing Shinzens and Mahasi's noting techniques and never picked up the "relax" and "smile" component. I also started doing metta based off of Bhante Vimalaramsi's youtbue videos and I have started enjoying my meditation again. 

I am thinking of going to one of his retreats and would like input from others who may have attended. 

Thank you for your time,
Jorge
