For having been an hospitalière in Conques, I could recommend you, if you wish to stay at the Abbey which is a neat place, to ask for the room 15, with a view on the abbatiale. If you want a more romantic effect, you can ask for room 1 or 2, which are at the top of the tower, right under the little oratory
(The view is of the roofs). Ask also if it will be possible to visit the top of the abbatiale, where it is wonderful to walk listening to Br Jean Daniel's organ music...
Otherwise, if you have the opportunity of stopping at one of the
gîtes of the Haltes de Compostelle (
http://www.haltesverscompostelle.fr/32322/index.html), you're pretty sure to get a fabulous welcome. You can also sleep in a yurt in Aubrac if this appeals to you. The owner is a fabulous woman. If I remember well, it is called l'Ange Guardien, The Guardian Angel. She knows medicinal herbs and makes fabulous healing oils. (

Otherwise, as other pilgrims before me have said, this is one of the most beautiful parts of the Camino.
Wishing you and your wife a wonderful time!
Bonne Route!
