I ended up with a private tour, being the only one who signed up that day. Ken was on time and was very knowledgeable. Because I was alone, we made more stops than scheduled, which was appreciated as many of the photo opportunities would've been only available through the window of a moving vehicle. Ken slowed to allow better pictures of sights as well.
I did not enjoy the stop at Fisherman's Terminal though. I was bored. I now see on here that wasn't even supposed to be the stop. It was supposed to be the Locks and Salmon Ladder. I don't even recall seeing those at all.
At the end, Ken dropped me off at the Space Needle as requested. I felt like I had a great overview of the city when all was said and done. I knew from what I saw what I wanted to focus on and revisit. It was a great way to start my trip to Seattle and get my bearings.
