Fellow educators having conferences at hotels or fellow educators having conferences on conferences at hotels?
Neither, actually, as it happens, but I'm laughing.
Not much of a fan of conferences, as most - and the academic ones were - mostly - uniquely underwhelming - were pretty grim. Academic males, in particular, a surprising number of whom were brutally bad public speakers, never knew when to shut up, or how to craft a speech.
No, these days, I am more often to be found in what is described as the real world, as I am an academic who sort of strayed into public service, although occasionally I will seek refuge in an Ivory Tower.
