I've been up to Jiminey 4 times night skiing this year and loved everytime. The stars were great to look at and conditions great. No people on the slopes is so much fun.
Sunday I went up for a Potter Brothers Flex day. There was also a Race going on so the amount of people was very high.
Surprisingly with the amount of people the lift lines moved fast.
Around 2 - 2:30 the upper slopes turned real icy, the outside slopes were still very enjoyable.
The atmoshphere is great here.
