Sure you can drive and find hotels/motels and bed and breakfasts along the way. In some cities during summer you can rent student rooms per night in the dorms of universities. Clean and cheap. If going to a slower area(thru the prairies) call ahead and make reservations. Plan your amount of driving to coincide with a stop where there is accomodation. I have never had a problem. Just understand you can drive hours thru the praires and find 1 or 2 gas stations and thats all. The villages aren't even that. But stick to the transCanada and you can find accomodation. Remember folks to try to plan the day without the sun in your eyes, So for anyone going east to west-get up early and try driving your 8 hours before the sun starts to get in your eyes. Trust me-its a good way to do it.
