I'm planning a college tour in the PNW and hoping to drive from Tacoma to Walla Walla then Portland. Am I being overambitious thinking the 'drive time' on Google maps is accurate?
Tacoma (Washington) ⇨ Walla Walla (Washington) Portland (Oregon)
The google travel times are generally accurate. You could do 3 schools in 4 days. It will be non-stop travel and a bit hectic. But, it is totally doable.
