I personally go to winterplace on their BSA weekends. Makes the lift tickets only 35 bucks, but when you go there's far too many people in the afternoon. If you want to actually ski more than one run per hour, I would go as early as possible. The staff are mostly college kids trying to earn a buck on their breaks, so not the most mature or helpful. The lodge is always overcrowded and is ususally filled with middle schoolers "taking it to town" with their girlfriends. I'd say go either early or late. NEVER between 12-6.
