We've done a fair bit of traveling in Ireland, where it is easy to find an available B&B when you're not sure where you will end up by the time the evening rolls around -- just start looking for the signposts which show the way to B&Bs in almost every town. Just drop in, ask if there is a vacancy (usually there is), check out the room, and they are almost invariably in the same price range.
We will be traveling to Wales for the first time this year. My question is, is the B&B experience in Wales similar to that in Ireland, or is it advisable to have reservations for each night?
Thanks in advance.
