that just got me so excited...
i now declare this the 2011- 2012 mountain creek thread
It can get pretty bad on Saturdays for sure but you can usually snake the line if your good and its not that bad at all (maybe 5 mins) and they also have two high speeds on the side of the mountain where the park is and usually one (bear lift) isn't that bad at all and has decent features. The high speeds are awesome.
I would guess Fridays are a little more crowded then oMon-Thurs but no there won't be lift lines during the day. HOWEVER, all the high schools in the area have weekly bus trips to creek on fridays after school (so they get there 3-4ish) and it really gets packed by around 6-7ish until closing with all the high schoolers and peope after work. Probably the worst time to be at creek, the crowd sucks.
But yea if you plan to leave early on fridays and stay till it gets dark it won't be too crowded during that time.
Creek is awesome cause its 100% night skiing but then again it sucks doing park at night imo so its better to go in the day when its empty and light out and the holes of death haven't formed yet.
