Maybe...but there wasn't. They said upfront that there would be limited and not to wait. He waited, he and you are blaming them.
Well, it doesn't matter to me...I don't ski there. I do feel bad for my friend since he knew the area and felt safe letting his kids go off on their own from time to time.
However, I do feel the only alternative being offered (the 3.5 hr session tickets) are over-priced and crazy for what Wachusett is (very limited terrain and trails). They basically have two partial length beginner trails, 3 off the summit, and maybe 4 off the Minuteman lift that go half way up the hill. It would be cost prohibited for him to buy those session tickets for his family, drive to the mountain, and not have a full day there. Remember, you say 4 hours would be enough for you, but try maximizing your skiing when dealing with 4 kids. I have skied with him and his family. It is like herding cats. You really need to be there a full day. Ski a little, hot chocolate break, ski some more, lunch break, ski some more, hot chocolate break, ski some more, heard the cats to leave and hope you are not forgetting one of the kids or their equipment! And that is if the weather is nice. Now, try doing that in 3 hours.
Again, doesn't matter because he picked up Epic passes for the entire family and plans to ski mostly a Crotched Mountain NH, which is only 30 miles from his house in Ashburnham, MA. Crotched has the same vert as Wachusett, more trails, and is never crowded. Actually, this may have worked in his favor
