Traveling to the UK next year! Need accomodation advice [View all]

My husband and I will be there for over two months with a specialized tour in the middle of our time there. We will start in Glasgow, tour Scotland, Yorkshire, and Lincolnshire before the tour. Then we will be in London for a week, and move on to Devon, Cornwall, Wales and other parts of southern England.

Originally I was looking at renting cottages for a week at a time in the middle of the areas we want to visit and had looked at Sykescottages.com and cottages.com. While the cottages they list look great the reviews of the companies are terrible. I thought about AirBnB but their reviews as a company are worse.

So now I am checking out combinations of bread and breakfast facilities and hotels. I am confused by the room designations.

When they say "double room" without listing the size of the bed, does that mean a double bed? My husband and I are large people and we're used to a king size bed. A queen or double would simply be too small!

Because of past health issues I need a shower and not shower above a bath tub. Can I reasonably expect any traditional B&B to have that?

Any suggestions for the best place to search for my needs and book rooms? I've looked at Hotels.com and TripAdvisor.com for reviews but never booked with them.

Thanks!
