I saw your original post, and I'd been meaning to ask: I've never heard 'lifestyle' in that context before - I've only heard it as a euphemism for a swinger club. Do you think that the blogger was also thinking in that direction?

Granted, in trying to figure out how to answer the snack bar lady's query of "what is this convention about?" I ended up telling her it was a gathering of like minded people with lots of different sorts of interests.
