I agree Jan 1 should not be busy. Windham has more intermediate terrain and Hunter has more expert terrain.
For Sat Jan 2 - I would recommend Belleayre Mountain
for a less crowded trail experience and high quality snow conditions. Again its important to get there early for high quality morning snow. Park at the upper Overlook lodge. Ski the SuperChief High Speed Quad with blue trail Roaring Brook and Onondaga off the top from 8:30am to 10:30am. AFter that head west to Lift 7. Take lift 7 and get off at midstation to take Tomahawk crossing trail west over to the Tomahawk lift. Take Tomahawk lift to top for blue intermediate trail Deer Run or enjoy the ever popular single black diamond Dot Nebel trail.
