Pattii, when you have walked the Camino you will find that albergues mostly take care
not to get infested with bed-bugs and to
eradicate them when they do get a report. You seem to think that they do not care. In Galicia the 6€ nightly charge gives you a disposable sheet and pillow case. The bugs are not confined to albergues, they travel on packs so theoretically could be picked up in a cafe-bar too
We have always checked the beds in private rooms as well as albergues and (so far) have not seen any evidence of bugs. Noise is not confined to albergues either
. If you are using a tent then you face will different challenges than these, not least getting warm and dry if the weather is cold or wet. Speaking personally I would rather be warm and dry, but we each make the Camino in our own way.
Buen Camino
