No experience of Epinettes at all, not ever, sorry. I'm sure somebody will be able to help soon, there's not much the collective experience of CA can't address regarding Le Mans. There's sure to be info elsewhere on the web if you can't wait though and the worst I've endured at LM, Beauséjour in a tiny igloo tent in pissing rain, unmarked pitches, no power hook up and 'indifferent' facilities was an experience shared with my missus and we still enjoyed it, relatively speaking.
Mrs Starbar should take a chance and go across, what's the worst that can happen?
