This sounds like an absolutely fantastic experience and certainly one that I would like to enjoy if my budget could stretch that far (or if EOS ever accept BA staff travel tickets).
The only thing I wonder though is whether EOS may eventually become a victim of their own success??? If EOS ever increase frequencies, take on larger aircraft or, indeed, begin to enjoy near-100% load factors, I fear that many of the more personal touches you enjoyed may become less common. Furthermore, had there been a problem with any aspect of the pre-flight preps at STN, I doubt that the station manager would have had a chance to visit.
Yes, they sound absolutely fantastic, but I fear that this level of excellence will be a struggle to uphold.
