Stower asked, 'Or are there any non-b&b-running 'Catters who can contribute what they like and dislike in a b&b?'

My husband and I have been to the UK and to Europe many times. We quickly stopped using b & b's. We disliked the b &b philosophy of 'You've had breakfast. Now get out till sundown.'

It's even worse that hardly anybody tells travellers that there is such a rule. No, the b & b industry just lets the naive innocent walk in and encounter a wall of hostility.

Another thing we disliked was having to inform owners that we wanted to take a shower. As if a shower was a rare and bizarre occurrence.

So we quickly promoted ourselves to the 'guesthouse' level of lodging and finally to hotels.

If I were you, I would get a job in the hospitality industry for a while to learn the ropes and see if I liked it. The idea posted above of reading books on the topic is also a good one.
