Oh Janice_ I'm so sorry to hear that. You are not alone in having to give up travel. I've had to bite the bullet and tell myself that I had a good run and saw a lot of the world. In my case, it's balance issues and my fear of falling. If I had someone compatible to travel with me, someone I could stand to share a room/cabin with, I might try it. But as it is, I'll manage a little within the US visiting friends and family and getting wheelchairs in the airports.
That Alpine Village tour is listed, but as Romantic Villages of Alpine Europe, or something like that. And it's sold out for 2014.
