Just did a week in Tahoe and did 2 days each at Kirkwood, Heavenly and Northstar. My order of preference is Northstar, Kirkwood and then Heavenly. Depending on which side you go up on(CA or NV) can be a big factor on how much walking you do. Also if you go from one state to the other be prepared for long CAT Tracks. Heavenly also gets more wind than the other two so be prepared for wind holds or closures. Of the week we were there they had wind holds 4 days and 1 day they just shut Heavenly down at 11am due to the winds.
