Seattle's skyline is iconic, thanks in part to the Space Needle. This 605-foot tower offers panoramic views of the city, mountains, and waters. Advise clients to dine at the revolving SkyCity restaurant for a meal with a view.

Pike Place Market, one of the oldest continuously operated public markets in the United States, is a bustling hub of farmers, craftspeople, and merchants. Travel advisors should recommend the early morning hours for a less crowded experience and remind clients to catch the famous fish-throwing spectacle.

For art lovers, the Seattle Art Museum and the Chihuly Garden and Glass offer world-class exhibitions. The museum's diverse collection and Chihuly's breathtaking glass sculptures are must-sees.
