If you are looking for a supported tour, you might contact Marly Camino. I used them on a Camino from Sarria to Santiago (they have others) with my wife and four friends (mostly ladies) last April. They use a small bus to support the walkers. They meet the walkers with the bus 3 or 4 times during each day (usually at a cafe) to ensure that everyone is doing okay. Your wife could just stay on the bus and then would be able to be
a part of the Camino experience during the day, especially the best part, sitting around at a cafe drinking cafe-con-leche with everyone. It would certainly beat sitting around at the albergue waiting.
Their guides and bus drivers are FANTASTIC. If you decide to do this, you might ask to be on a tour with
Victor as the driver. He is a wonderful, wonderful, human being.
Good luck in whatever you do. I truly admire you and your efforts to include your wife in your camino plans. My wife is not a "hiker" by any stretch of the imagination, but that camino experience has really meant a lot to her.
I am not in any way associated with Marly Camino nor receive any benefit from recommending them. I just know that they might have what you are looking for.
Buen Camino, Beachcomber.
