The most unsettling part of the Seattle Underground Tour experience is the lack of accomodation for those who gain mobility through the use of wheelchairs, walkers, canes, and other assistive devices. If you are a person who utelizes these mobility aids, please be warned that this tour is most likely not for you.
The tour begins in Pioneer Square, where you gain a breif history of Seattle and how the Underground portion of the city came to be. You then take meandering walks in the underground part of the city which I found very interesting.
I wish that the tour guides would have cut out the hammy jokes and you could tell that every tour group had to sit through the same un-funny jokes. Perhaps I'm being snobbish, but I can only take a joke about "John Crapper being the inventor of the toilet" so many times on the same tour before it just stops being funny and starts being annoying.
I thought the historical part of the tour was fascinating, but the tour itself was a bit boring and long-winded. Again, not for those who cannot walk for long distances or need wheelchairs, etc, as the tour cannot and will not accomodate people with those needs, which I understand to a degree, but find disheartning at the same time.
