I was on the grounds the day Music Experience opened 7/23. It really wasn't that busy because (1)the $20 admission & (2) everybody seems to think that everybody else is there & it's too busy. Not the case.

Good hotels SEA downtown are Alexis & Best Western Pioneer Square, on Yesler.

Took the underground tour & while it was interesting I could have done without it. Check out the content first. AAA suggests it, but many other guidebooks omit it.
