I posted similar message at Vancouver forum, people suggested me to post my questions on road trip forum. Here are my message and questions:
We are planning to hire a car for 4 weeks In May/June from Vancouver to Vancouver Island, then drive down from West Coast to San Francisco, then via the Rockies back to Vancouver. We had a look some rental car websites, it appears there is limited on km (200 km/ day) outside the state and neighbouring states. Exceeding the limit, a charge will be applied.
We would like to know if we can hire a car with unlimited km no matter what state we drive to. We consider hire a car in USA like Seattle or San Francisco if we can hire an unlimited km car. We just have to alter our itinerary.
If we need to hire a car in SF or Seattle, can we return the car in different location or country (Vancouver).
