Thanks again for so many responses. I was hoping deep down to have my concerns nullified and that my suspicions were completely wrong. After all, I've learnt so much from this teacher, but as I look beyond the guru worship facade i'm beginning to feel more and more uncomfortable about what's going on.
I've gone to the Palyul Nyingma international website and there's absolutely no reference to this institute on their authorised centres page. Which is very strange as Rinpoche speaks so much about how close he and HH Penor Rinpoche were and of all the grand work he does / did for him. I've sent the International Association m an email requesting clarification on whether this centre has been directly authorised by HH Penor Rinpoche.
It's funny but the Pathhgate website says that it is a member of the Palyul International Sangha, yet all the links on their website to the international sangha and regional centres go to sites that have been setup by Pathgate themselves, not to the Palyul Nyingma sites operated by HH Penor Rinpoche's foundation and his authorised teachers.
The charge was 495 pounds per week, which equated to about $1000. This is in stark contrast to the authorised Palyul Centre UK's charges (suggested donation) of 5 - 10 pounds for their hour and a half long dhamma talks. The 495 pounds does not include accommodation. http://www.pathgate.org/pi_Summer_Retreat2012_03.html
I don't know, the more I read objectively into this the more my concerns grow and I'm still hoping deep down for someone to refute this with more than a reference to how many hits a ridiculous youtube video has gotten. Regardless of whether this was true (I've been in one of those workshops and it only worked when I so desperately wanted to believe that I jumped and convinced myself it was something else), didn't the Buddha prohibit Bhikkus from displaying iddhi powers in front of ordinary people due to the dangers involved - I'm sure this is in the Vinaya somewhere?
