If the MAX is at BFI, you can easily spot around the area from different areas, including the main terminal. Some FBO's offer a decent view as well. Of course the Museum Of Flight is a necessary stop. Maybe you might catch a glimpse of a MAX doing some test flying!
Paine field is a bit of a pain by the way. Of course they do offer a factory tour, which also comes recommended. They also have a very small museum from where the tour bus for the tour picks you up. Lots of cool displays and Interactive cabin mockups. They also have a cockpit section of a 727, which you can sit inside and play with all the controls. Spotting is a bit tougher at PAE. It's a massive airport, but not very spotter friendly.
Renton is probably the dullest in terms of spotting. Not much activity, besides an occasional 737 leaving. More GA aircraft activity. Not much in terms of getting any really good views of the 737's.
SEA itself is fun, but no areas really specialized for airplane nerds. You can find a park at the north end of the runway near the employee parking areas. For the South end, there are some industrial areas where you can spot from. I wish SEA would put a spotters area out there! I like LAS off of Runway 25. It would be great if SEA would do the same.
So, if action is in your books, Boeing Field and the Museum Of Flight will offer a full day of fun for sure! Have fun, and hope the weather holds up for you! Hope this helps a little!
