Hi, we are a family of 5 planning to visit CR in late august to early sept 2011. We are arrivng at and leaving from vancouver. We would like to consider the rocky mountaineer train journey as well as driving on the return journey. Vancouver to banff by train then driving to Jasper and back to vancouver by car. But I notice the one way car return on Avis is double the price if the car is returned to the same location as pick up.
