What's the best (that is, least exciting, er, mountainous) route to get from Seattle to Jackson, Wyoming? DD is having surgery in Seattle, and after we get her stabilized, we want to go to Jackson to visit DS for a couple of days before heading back to Wisconsin.
Edited to add we will either be driving a front-wheel drive Audi or a 4WD Trailblazer.

Traveling with Poodles: Oscar the toy and Felix the mini
Tow Vehicle: Chevy 2500

Chase Vehicles: VW GTI, Audi A3
Unless you WANT to go thru the park, best way to Jackson is I90 to I15, south to Idaho Falls and then over to Jackson via 26 then 191. You will avoid the entry fee and hastle of tourists in the park.
