Thanks to SuzyQ for the contact at GdF, I will contact him straight away. Thanks to all for the feedback. Maybe the estimate for high season is too high (95%). But it is the low season (10%) which could be most significant, as it covers most of the year. If we could achieve perhaps 15 or 20%, that could make the project viable. We have some ideas on specialities to attract guests, but nothing definate as yet. We would not be targeting the British exclusively, we would hope to attract french people on long weekends, etc. I speak french, my wife does not but is starting to learn. I guess most guests come from passing trade, rather than pre-bookings? It would make sense therefore to be fairly close to a main road, where one can put an advertising board.
