A couple years ago my wife also got tired of working in a windowless, bunker-like office for an undisclosed government entity in Washington, D.C. and took a 6 week sabbatical to walk the Camino. She got summoned for grand jury duty while on the trail and came back to an immediate 6 weeks of that.
Returning to work after 12 weeks of being off she decided it was time for a career change. She now works at a slightly different windowless, bunker-like office for a government entity in Washington, D.C.
Point of the story, enjoy Spain! If it were me I'd probably pick somewhere else to cycle or just walk the Camino and enjoy the company of everyone else. I did have some neighbors that biked the Portuguese route of the Camino earlier this year and they really enjoyed it.
