We got off our cruise ship and needed to kill a few hours before our flight, so this was one of the things that we did. The nice thing is you can buy tickets but they are good for a year, so you don't have to use them right away.
This is fairly close to Pike Place Market (a little under 10 min walk), so we were able to buy the tickets, go do a couple things at Pike Place, and then head back here to catch a ride. There was a crowd but it was only a 10 minute wait to get on, so it wasn't bad. They do let you drink in line and on the cart, but the beers are $12 (yikes) and you have to finish it once you leave the pod. So, it might not be worth it. They were fine with regular non-alcoholic beverages, so no worries if you got your water bottle handy like me!
The ride itself is cool. We got a pod by ourselves (just me and my husband) so we were able to see the city and the water by switching sides. We could even see our cruise ship that hadn't left yet for the next crowd, so that was pretty cool. You go around 3 times and the ride takes about 10 minutes.
Since I live in Vegas, it's hard not to compare this to High Roller, which costs slightly more, but is longer. I think this worked well for our limited schedule, and you can see quite a bit. I feel like the High Roller is a little more of an experience, and you can do it at night. So I think it depends on how much time you need to kill. The weather was pretty nice in Seattle when we rode the wheel, but I wouldn't recommend it if the weather is crappy.
