Many hotel/motels have free wifi included for guests, and some have a small daily charge for use.
If you are going to a larger city or populated areas the coffee shops/cafes usually have wifi some free and some a sign up & small fee.
I would do search for wifi hot spots in the areas you will be traveling to and see what comes up , also check the various hotel/motels that you might be staying at.
