This is a general reply only. Most hotels/motels along the way will have an adjoining parking area for guests, generally free. Parking in the big and medium-sized cities generally means feeding coins or a credit card into a meter, or going to a parking lot with an attendant. Newer meters typically accept MasterCard and Visa, but most meters will take 10 and 25-cent coins too. Rates vary widely, even within cities. The smaller towns generally don't have meters and parking is free.
