If you have the time and the money, a trip to Tillicum Village that includes dining and observing some of the Native art. I haven't been in downtown Seattle for some years, but believe they still sell tickets right there next to Pike Place Market. Check with the organizers of the medical conference and ask about discounts for anything. My outings usually involved taking visiting family members to Pike Place Market, Northwest Trek, drive up to Paradise at Mt. Rainier. A ride up in the Space Needle to enjoy the viewing deck does not mean you have to eat there. I much preferred eating down near the water. You can also take a ferry to Vashon Island, where I believe I recently read of the re-opening of a quilt shop over there. Google "NW Washington Shop Hop, 2015". As your daughter already knows, getting around in Seattle is not easy. Bring comfortable walking shoes for all the up and downhill walking. I often saw women dressed in beautiful suits or dresses, wearing beat up sneakers and carrying dress shoes in a shoe bag.
