My partner and I run a guest house in Bridlington and don't have a problem with one night stays at any time of the year.
We have an ad on the
Way of the Roses website. Obviously I can't give details of our place on this forum as I'm sure the forum admins would pull it, and it's not really ethical. You'll just have to phone around those listed.
We are members of the CTC and Rough Stuff Fellowship so like to think that we a fairly cyclist friendly.
What sort of prices are people being quoted for transport of cycles and gear to/from Bridlington? We have 17 seat miibus which I could strip some seats out of to make space for bikes. Could probably fit eight cycles and passengers but I'd have to check of course.
