looking for some advice and guidance of itinerary for 2 weeks, next June.

would like to get out to Banff, Calgary, Jasper part of the world.

thinking maybe a couple of days in vancouver to get over jet lag, then get on the road out east and then blitz the drive back to vancouver, or do half on the way out, half on the way back.
or should we look at flying out to say calgary and getting a one-way rental back?

any advice on what is going to be a decent amount of time to spend in each area and along the road.
would like to do a bit of hiking, nothing extreme, a bit of canoeing, some relaxing, something fun for a kid aged 7
also anything that is recommended avoiding

thanks!
