Alamo are £300 more expensive for the weeks we want from Vancouver , I know it is pot luck what you end up with but we can get to the airport early in the morning and ask nicely. As there is no rush ( we are landing two days before and staying with friends before heading down into the states) we can get there and see what is available,
Oh Canada, fair enough. I am using Avis for Canada too.
Note that in Canada it isn't zero excess.
