Q:

Long walking trails in Europe with accommodation enroute

What waymarked walking trails in Europe allow you to stay in hotels/guest houses/b&bs every night along the trails? 
I'm looking specifically for way-marked trails that you can walk along for 5 or 6 days without having to carry camping equipment, and instead stay in hotels every night. 
I know that there are hundreds of walking trails in Europe, but the majority of them, you can only walk for at most 2 or 3 days before you have to go more than a day's worth of walking to get to the next hotel. 
What walking trails exist that allow you to do this?

A:

In Spain you have the Camino de Santiago. This is what I wrote about it in another Travel question:

You are looking to walk the Camino de Santiago. It joins hiking,
  nature, historic architecture, photo opportunities and is very cheap
  (eat about 6-8 € per meal and sleep 4-8 €). Additionally, you'll know
  the real Spain, meet interesting people (mainly Spanish, but you can
  find people from around the world and you will complete one of the
  mythical mid age routes.
Depending on the time you have you can start from one city or other.
  For instance if you have 2-3 weeks you can start walking from Leon.

You'll find cheap accomodation in nearly every village you cross. You have a lot of guides (printed or online) that will help you to book hostels (but, believe me, if you are not going on peak season it is not necessary at all).
Depending on your time and interests you could start walking on one or another place. The best is you read any guide to know where is the best place to start walking for you.

A:

You can find informations on french GR-Info site. It is about long distance footpaths  in France, including contact info on accomodations.
For instance, GR-10 crosses the Pyrénées mountains from Atlantic Ocean to Mediterranean Sea, or GR-20 around Corsica.
