The Seattle aquarium is really nice from what I remember. I am pretty sure they have expanded too. I would check out there website. I absolutely loved it when my Dad took me and a friend one summer.

Then there is also the Woodland Park Zoo in Seattle
They have a Retic and an Annie there. The last time I went I think it was the Annie that I saw and it was HUGE. I could be wrong though, it may have been another Snake.

I will email my Dad and find out if anything is going on that is kid friendly. If I can even get a hold of him. I still haven't heard from him since the gecko thing. Who knows though with him.
