I have a business appointment in Portland, and another in Seattle. I live in NC, have tons of vacation I have not taken - so am thinking along the lines of a combo trip.

My thoughts are:
fly to Portland on a Saturday, drive to Crater Lake, spend remainder of day, all day Sunday, and most of Monday....then return to Portland.

On Tuesday, I would have my Portland biz call in the AM - then drive to Seattle. Wednesday I would have my Seattle biz call, finishing by 2PM or so. That would leave remainder of Weds, Thurs, Fri, Sat and Sun for activities in Seattle, Olympic Peninsula, etc. I have seen all of these things - my sister lives there - so have to factor in visit time with her.

But that doesn't give me much time in Portland proper - which I have never visited. Also really does not allow for a leisurely drive Portland to Seattle - should I allow time for sightseeing on the drive?

I can add a day or so on either end if need to do so - but need to hold the trip to about 10 days due to other appointments which bookend the trip....

TIA for your assistance....
