Having a bed and breakfast holiday is something that not everyone gets to do, and a lot of people don't do it simply because it really doesn't occur to them. They opt for the glamorous hotel instead, but when they do that they don't realize what they are missing by avoiding a bed and breakfast opportunity. When you go to one of these establishments for your holiday you'll be greeted at the door, and the same person who greeted you will probably be the one serving you breakfast the next day, so you won't feel isolated or like you don't know anyone, even if you're taking a holiday alone. It's a great way to get to know someone who lives in the area and you often meet and talk with fellow travellers, as well.
If you have your sightseeing already planned out you're in good shape, but if you're not sure just what all you should see, you can certainly ask. The people who own and operate bed and breakfast establishments generally know where all of the good things to do are, and with that being the case they can fill you in on all kinds of things that you might not have known about otherwise.
If you have things planned out, tell them your plans and see if they have suggestions that you might want to consider as well. If you don't have things planned out, ask them what they'd recommend and then see which of the recommendations best fits your idea of fun on your holiday. You don't have to do everything that they suggest, but since they live there they will certainly have a good idea of what to do and see in their city. With information from someone who runs a bed and breakfast, Bath is at your fingertips much more easily and quickly than it would be if you had to research a lot of different places just to try to figure out where you wanted to go first. It can be very confusing in a new place, and if you're travelling with companions who have different needs - or with small children, the elderly, or the disabled - things will be much different because you'll be more limited in what you can go do and see. Let those who have lived there for a while help you out. You'll be glad that you were given suggestions to choose from instead of getting overwhelmed with everything.
