Sleeping with 25 of your closest new friends in an albergue is one of the seminal experiences of the
Camino Frances. The coughing, the snoring, the farting, the squeaking bed springs, the threat of bed bugs. Ah, how I miss it.
No, not really, but it IS one of the seminal experiences of the Camino. Of course, you may want to get away from that very occasionally.
Get a room in a pension, a casa rural, a hostel, as others have recommended. Don't worry about missing out on sharing a communal meal, you will have lots of opportunities for that. Enjoy the quiet rest, the chance to recharge your batteries, both literally and figuratively, in security and comfort.
Many people plan to spend an extra day in the main cities along the way and those days were in hotels or pensions of necessity. Albergues require that you leave at a certain hour of the morning.
Personally, twice I had to stay in a single room because the albergues were full. The places along the Camino are full of pilgrims. You will see them everywhere with their backpacks or walking around in socks and sandals.
As much as I enjoy having a clean bathroom all to myself, the tales you return home with will most likely be more about the albergues than the hotels. I wouldn't trade it for anything.
That being said, I blog about my Camino and my next posting is tentatively titled "The A*Hole in the Albergue." Yep. Lots of adventures.
