Late to the party, but...Berkshire Ice is a GREAT place to ski on holidays. There's minimal lodging in the area, so it's all local traffic and does NOT draw vacationing crowds. Sure you get the ski racers, but they tend to congregate on a very small number of runs. Next to no lift-lines, even on the morning after a major powder dump on President's Weekend.
BEast is my local hill (not my home mountain, though), but I avoid it unless there's been a good quantity of natural snow in the past week or so. Their snowmaking and grooming is not, shall we say, a major selling point for the ski area. Also, if what you're used to is Wachusett, BEast may come as something of a nasty shock. Given the vert, it's very steep, and the trails are your classic New England experience (narrow, steep, and icy) and the ski area's attitude towards trail signage can be summed up in the old chestnut "If you have to ask, you're in the wrong place". The Berkshire East greens are not a lot easier than Conifer at Wachusett, and the typical blue at BEast is on a par with Wachusett's 10th Mountain. The front blacks are comparable to Upper Whirlaway or Wild Turkey at Jiminy.
If you want a low-key, crowd-free, relatively inexpensive experience, and you don't need to stay right at the ski area, and you're comfortable on advanced trails at places like Jiminy and Wachusett, it's a great ski area for a day trip.
