Apologies if some of the following has been answered elsewhere.

I am traveling to Canada in April this year.

Wanted some advice on

1. Car rental - Is it cheaper to book online or when I get to Vancouver? Also gather that the airport is a location that attracts prime location surcharges.

2. Accommodation - have been looking thru the Lonely Planet guide that has lots of info but what chains offer vouchers for accomodation over a period of about three weeks?

Any titbits of info welcome.
