We've done fly drives in USA before and there's plenty of budget motels around. Is it the same in Canada? We're thinking of flying into Vancouver and out of Calgary the first fortnight of September. Is it best to work out a route and pre book hotels/motels or is there plenty of budget ones to just call in on the way? This will keep us a bit more flexible. We've stayed with family before in Vancouver and done a ski holiday in Banff but never toured around in this area and I want to see Jasper, Yoho and some of the Rockies in the summer.
