Cruise is great, but you really need to layover a few days to enjoy and explore the landing spot. You can only scam the surface if it were a one day stop. If riding bicycle is something you enjoy doing , then bike around the bicycle route will allow you to see everything. For goodness sake, the Seattle council tried to make Seattle a bicycle friendly city, at the cost of everyone else.
We had been up to the B.C area severs times a year for the past 20+ years and still finding new things to do. Same with the Puget Sound area, almost a native here for close to 46 years rooting but many new comers had been to places where we had not been yet. My wife used to tease me that I'm too homey.
One negative here is the traffic, getting really bad anytime of the week. A price to pay when population growth is not properly managed. Or can it be managed ?
