If your passport is lost or stolen, the copy can be faxed to you, which will facilitate the process of getting a replacement. Decide ahead of time if you mind sharing a bath or not. If not, you can save even more money. If I book through a central agency, I always call the proprietor ahead of time and ask him or her more specific questions as needed. Two other ways to save lots of money on lodgings is to consider hostels or camping.
Many hostels now have private rooms available in addition to dorm-style rooms.
They are not for everyone. Unfortunately, in some places, this is either limited or impossible. I also realize that for some readers, physical problems may make using public transit difficult or even out of the question. In some instances, buying a pass gets you discount admissions at tourist attractions. You won't worry about finding a parking place, feeding a parking meter, or wonder if the car is being towed.
