So I went a few weeks ago and had a wonderful time! Only slightly rained on one day. Underground tour was fun and so was the waterfront. Nice place to visit...
Being an out of towner, the most interesting thing that I have done here in Seattle was to come through the Strait and Puget Sound into Elliot Bay on a fishing boat. I found the Seattle Aquarium some what interesting as most of their species are natives like rockfish, skates, salmon, halibut and other cold water species. They do, however, have some tropical tanks and a huge touch tank area but I really didn't think it was worth the $16 admission charge. I really wasn't impressed by Pike Place Market either.
