I am going to Canada in May with 3 friends for 2 weeks. We are aiming to visit Toronto/Niagara, Montreal, Quebec and Ottowa. We read you can get soemthing called a Corridor Pass which gives you a 10 day train pass [I assume this is unlimited travel]. We are considering hiring a car instead though as would be so much easier and we don't have to stick to a timetable. The train pass would be £450 for the 3 of us, is it going to cost us more/a lot more to rent a car and for insurance and petrol etc? Any advice/experiences would be great.
