We are planning a trip to Scotland in the summer of 2019. In preparation, 30 years ago, or so, when my parents moved us to Scotland I remember my father having a B&B book from which we booked accommodations for the next 4 years. Has anyone used such a book recently or have recommendations.
We used a B&B book on our first trip to Europe in 1989 !
Now, to find the top ranked B&B's, I use Tripadvisor and click on B&B on the left side instead of hotels. You will get their ranking of B&B's. It is a start !
Also, you can look at bedandbreakfast.com.
There is no point buying books which are out of date before they are published, when there is so much information available online these days.
Look at sawdays.co.uk, Trip Advisor, Booking.com or smoothhound.co.uk for B&B options.
Don't forget to look at Google maps as well.
