Now I know where LFAT is...
I have a leaflet with Le Touquet hotels which I picked up at the airport. If you send me a pm I can let you have some phone numbers if you still need them. We stayed at the Nouveau Caddy - small, friendly English speaking, right by the covered market...a few rooms with picturesque round windows looking out on to the market. Not luxurious, but I'd definitely recommend it for friendliness, ambience, etc.
