Any thoughts on a driving trip from Seattle/Vancouver to Banff/Glacier Park in MT and then Yellowstone with a return to Seattle in a two week period.
Driving conditions, time allotted?? etc?
Is it too much for the two week period of time?
Thanks.

I think it would be very doable and a nice trip, allowing 3 days in each of the parks. From Seattle to Banff/Lake Louise is more than a one-day drive, but you could break it up with an overnight in Revelstoke, or along one of the lakes. From Banff to Glacier NP is a full day's drive, and from Glacier to Yellowstone another (very) full day). Most of the above would be on good 2-lane roads. Yellowstone back to Seattle is more than even I would drive in one day, but you could stop in Coeur d'Alene, Idaho. From Bozeman to Seattle it is all freeway (I-90).

Total. . . 6 days of driving (2 of those only partial days), leaving 8 days to spend in the parks.

What time of year? Do you have to go in and out of Seattle? Can you start in Vancouver and leave from Seattle or somewhere farther east? Have you been in the PNW before? Are you interested in the islands at all?

You've picked gorgious parks, but there is a lot of driving. Glacier and Banff are quite similar, though Banff is much larger. With limited time, I'd say visit either Banff or Glacier, not both. Glacier is easier to get to, but Banff is larger scale. How about this?

Day 1: Seattle
Day 2: Vancouver
Day 3: Vancouver, drive to Hope BC for night
Day 4-8: Banff, hq Lake Louise
Day 9: Drive to Yellowston, stopping somewhere for night enroute.
Day 10-12 Yellowstone
Day 13 Driving back to Seattle
Day 14 Seattle

Way too much driving for me, but it depends on what you want to do/see in the parks. I would save Yellowstone/Tetons for another trip.

Agree with Enzian, a nice trip.

If you're starting in Seattle, don't go by way of Vancouver (unless it's a priority) since it's actually farther west than Seattle and is a longer drive to Banff. Instead, I highly recommend the route we take - either I-90, US 2,or SR 20 (choice depending on how fast you want to go) east to Spokane, then north on US 2 to SR 211/SR 20, then SR 31 up through Metaline Falls to the border - a really scenic route through Pend Orielle County. Overnight in Nelson, BC, a very cute town (used in several films, e.g. Roxanne with Steve Martin) then follow BC Rtes. 6 and 23 up to the junction with the TCH just west of Revelstoke NP. The Kootenay country (Nelson area) is gorgeous and relatively undiscovered by US visitors.

After Banff, you can go south on BC/US 93 to Glacier Park, then south on US 95 to Missoula (nice town) before heading over to Yellowstone. Or, if you've had enough mountains in Banff, head over to the Calgary side of the mountains and head down on AB Rtes 2/4 to pick up I-15 at the border, then it's a rapid drive down to I-90 at Butte, over to Bozeman and YNP is around an hour south of the freeway. Can be done in a day, or two part days.

YNP to Seattle is a good 10 hours on the road - doable in one haul or one and a bit. Lots of gorgeous turnoffs, however.

Thanks to all who responded. We have taken all your suggestions into consideration and feel that the drive time will eliminate some parks. We will probably do Glacier and Yellowstone and enjoy those two for this trip.
Again, many thanks for your time.
