Seattle Children's most definitely does NOT offer free parking. Nights, weekends, and holidays allow for employees to park on campus for around $3.50 per day. Normal M-F daytime hours, the cost depends on arrival time (going up to around $8.00 per day, I think). Driving alone - you park off-site and get shuttled in. Carpool/vanpool - you park on campus and split the parking fee between riders. Any alternate commute (bike, walk, bus, carpool, basically anything other than driving alone) earns a $4.50 commute bonus per day. They do offer a steeply discounted ORCA card for bus/Link commuting as well - about $130 per year.
