We will be in Seattle in March with three children (10,8,5). Looking for fun things to do.

What are you currently thinking of doing?

Woodland Park Zoo
Great Wheel (ferris wheel on the waterfront)
Aquarium
Children's Museum at Seattle Center
Olympic Sculpture Park
Ride the Duck

Bear in mind that March can be very changeable on the weather front - rain, sun, wind, repeat... so plan plenty of indoors activities as fail-safes.

When in March, and for how many days? Will you have access to a car? There are lots of enjoyable things to see/do within an hour or so of the city, for example in mid- late March, the daffodil fields in the Skagit Valley, maybe with a few million snow geese around too.

My kids were 10 and 15 when we visited this summer. I'm pretty sure the 2 best things for them were the needle and the pinball museum. The Star Wars and Scifi exhibits at the EMF were enjoyed also.

We didn't like the ducks. Ours broke down, but I was expecting more, I guess. It is mostly a glorified bus ride, on an uncomfortable vehicle. Then a short boat trip to see the house from When Harry met Sally, which is a pretty outdated pop culture reference, and meaningless to kids. It is far more interesting watching float planes take off and land.

The Seattle City Pass is the best bang for your buck... It gives you choices of about 10 attractions including the Space Needle, aquarium, EMP museum, zoo and a bunch more... www.citypass.com/Seattle
