Depends on what you want to do at destination. I've seen one campground, with a rental car.
Rentals in cities will rent you a car but it is a lot more expense.
When we get to a destination, we spend very little time, as a rule at the coach.
We roam maybe a hundred miles away or further, to fairs, antiquing, fishing, visiting friends and relatives. Sometimes I wish I had a van or truck towed instead of the Edge. You can out a canoe or small boat on racks on trucks and some vans or larger SUVs like Suburbans and can take all those gotta have its inside for the trip home.
