If you want to do the Future of Flight/factory tour.... buy your tickets online after you cross the unpredictable border. By lunch, the popular factory tour tickets are typically sold out for the day!

Google Maps states it will take you 90 minutes to 2 hours to get from the border to Paine field.
we bought our tickets online in advance..
we stayed overnight across the street from boeing in everett and only did the tour the next day (so we wouldn't be rushed driving down from vancouver)..
we stayed at the hilton garden inn (which is directly across the street from where you go on the tour)..
we thought it was a very nice place to stay and very convenient to boeing..
we overnighted there, ate breakfast at the hotel, checked out, then drove across the street to do the fantastic boeing tour..
after the tour we ate lunch at a great restaurant just a few minutes away on the water...
maybe it was called Ivers? something like that...fantastic fish restaurant..
and then we drove on to seatac for our redeye flight out of seattle..
so we rented the car in vancouver on friday and dropped it off at seattle airport on saturday night..(2 day rental)..
that way we could have a leisurely drive down to everett on friday and not worry about getting there in time for the tour since we only booked the tour for saturday....
a really lovely addition to our alaska trip...
and because we had so much time to get from vancouver to our hotel across from boeing..
and then so much time to get to seattle airport, we were very relaxed about our journey...
took scenic routes during the drive down from vancouver etc..
very enjoyable and worth the cost of the two day rental!!
As someone who works 5 minutes from Paine Field, keep in mind our traffic is pretty crazy!
.
yes, the traffic to get to seatac from boeing was INSANE!!!
and it was saturday....
where were all those people going????????????????????????
we kept asking that!!!
that's why it was great we took two days....so we were totally relaxed even in the crazy traffic jam!!!!
