I have been going to the Seattle Aquarium since I was a small child - and since the big window in the front was a wave pool where I tried to drop my little brother. The Aquarium has grown and changed - and is really wonderful. You enter right into a room with two very large "touch" exhibits, which is wonderful for children and adults alike. The other highlights are the sea horse exhibit, the salmon run (where, on season, spawning salmon go up the ladder above your head as you wind up from the lower levels), and this year there was a baby otter. You can see most of the aquarium in 2 hours, but spend 3 or 4 if you can.
