Dude! Count your blessings...really, do...
One is NEVER "stuck" in Bayonne, France. However, one CAN be stuck in Bayonne, New Jersey, USA. I know, because I grew up near there. Trust me, Bayonne in France is like Paris on the Bay of Biscay by comparison...
You will be on Camino soon enough. If this is the worst event that occurs during your pilgrimage, you are indeed a lucky person.
Each day brings new adventures, experiences, and learning. This was lesson "numero uno..." Learn to just roll with what the day brings.
Also, please remember that the first day out of St. Jean Pied de Port are the most difficult segment of the entire
Camino Frances. The first 8-9 km are very steep, right out of the proverbial "starting blocks." Pace yourself.
We all wish you a very happy, and uneventful Camino.
