Seattle Mariners. The Seattle Mariners play at Safeco Field, a retractable-roof stadium where there really isn't a bad seat in the house. One local sports columnist referred to the $656 million venue—which finished $100 million over budget—as "the guilty pleasure." You can purchase tickets through Ticketmaster or StubHub; online or by phone from Safeco Field (to be picked up at the Will Call); in person at Safeco's box office (no surcharges), which is open daily 10–6; or from the Mariners team store at 4th Avenue and Stewart Street in Downtown. Priced dynamically based on day and opponent, the cheap seats start at $16; better seats cost $36 to $120, and the best seats go for upward of $500. 1250 1st Ave. S, SoDo, Seattle, Washington, 98134. 206/346–4000;
