Seattle Southside Regional Tourism Authority (RTA) is the official destination marketing organization for Seattle's Southside including the cities of SeaTac, Tukwila and Des Moines. The organization is responsible for promoting the community as an attractive travel destination and enhancing its public image as a dynamic place to live and work. Through the impact of travel, the RTA strengthens the economic position and provides opportunities for people in our community. Seattle Southside RTA is funded by a self-assessed hotel fund and supported by a lodging tax from the cities of SeaTac, Tukwila and Des Moines.
