Tacoma has a decent public transit system operated through Pierce Transit. Buses carry passengers almost anywhere in Tacoma for $1.75 per ticket, valid for one hour. The ticket is bought on the bus and requires exact change. Day and monthly passes are alo available and can be purched on their website or at the bus shop. In downtown there is a short light rail taking passengers between the Theater District and Freighthouse Square, passing the University of Washington - Tacoma campus. It is free and runs relatively often. The buses do not run all night however. Express buses to Seatac Airport and Seattle can be found at the Tacoma Dome Station and are a quick and convenient way to get to Seattle since parking can be both dificult and costly. Cabs almost always need to be ordered in advance. About half an hour of waiting time after a call is placed should be expected.
