Seattle continues to be a top tourism destination, according to AAA, and the number of estimated visitors over the past six years may back that up. 

Earlier this year, AAA released what it expected to be its top 10 summer travel destinations. Seattle was seventh on the list and one of just two cities in the lower 48. 

The top destinations were based on AAA bookings for trips June 1 through Aug. 15. Of the top trends, Alaskan cruises are a top choice for travel, with Vancouver, Seattle, and Anchorage topping the list for departure.
