The summit is great, 45 min from downtown, and open till 10pm riding there is very convenient. 4 area's ranging from beginner slop of summit west, to the tree runs, & rock drops of Alpental The Summit has terrain for all skill levels. West & Central both host terrain parks, 2002/2003 season saw a explosion of new hand rails, & Jib boxes, making summits park better then ever.
Now the down side of the summit is it has the lowest elevation of the Western Washington resorts, so the snow is sometimes questionable. They don't lay out there terrain parks very well, although they put lots of hits & rails, the lines are often poorly thought out, and don't flow very well. Weekends the lift lines get a little long, especially if we get a dump. Alpental tends to be the worst for lift lines, there is only 1 chair that access the top, & 1 chair for the back bowls, but there is tons of tree lines & hidden spots you can catch fresh power long after a storm. Summit is well worth the trip, and with $300 for an unlimited season pass, you can easily get up there twice a week, and with seasons the last well into April there is no shortage of opportunities for going big.
