Given the insane-o prices of hotels in the UK compared to most other places in Europe, don’t rule out hiring a cottage … we go every year with friends and for four of us, hiring a whole house usually worked out the same price as B&B and then factor in the added bonus of privacy and a lounge / kitchen to hang out in. Ok, so you don’t get an expertly cooked full English every morning (unless you or the missus are expert full-English cookers) but I believe the pros outweigh the cons… you can also usually store the bikes in the living room* … which most B&B owners for some reason object to.
Can look at a few companies for the best bargains… Wheelwrights, LakeLovers, Welcome Cottages etc…
*Always remembering to keep them vaguely clean and remove traces afterwards, this is someone else’s property after all…
