scenario 1- if the march is the same as february (1 storm or so...with bad contitions) i would recomend Northstar because they have the best snow making and grooming and managed there snow very well..also the park is pretty good right now
Scenario 2- Tahoe gets the "miracle march" then go to squaw and alpine...alpine has sweet park and so does squaw sometimes..and they have super good terrain and lots of tree skiing at alpine...
Just all depends on conditions..and if u really want to ski park go to boreal for night skiing or for a full day always has a super sick setup
hope this helps
