The title of this conversation is a little misleading. David's interest seems to live with Romanesque architecture and not the Camino experience. Ex: the shell as the symbol of the Camino. Just because Santiago is close to the sea? No. So much more: legends about rising from the sea covered in the shells; early pilgrims' use of the shell for eating and scooping food; and so much more. Hotels? Good to know. But you can also stay in lovely family-run hotels with great meals and have your backpack carried from one to the next for six euro. Mentioned hotels in passing if you're close to a larger city but they're really all over the Camino.
I have enjoyed them in person and online for many years.
I think I am a member of your target audience--I teach Spanish culture at the college level and am involved in study abroad. My colleagues in related areas such as history, art, music, etc will certainly be intereted in many of the wide range of programs you offer.
I don't think it's for everyone, but surely for those who love to learn and travel. I really enjoyed it and can think of several friends who would really like it, as we can't travel and it helps on both sides of the tourism loss.
