I guess we are looking for blue cruisers and some steeps for learning. We also need an area for our friend who skis the blacks. I'm very familiar with Attitash, since my husband and I got up to the whites as many times a year as we can (love hiking the presidentials). But I think we were looking for a bigger mountain that had longer runs.
Sunday River may be what you're looking for. It has all those peaks, and they are really different from each other in character. It used to be my favorite resort. You'll find lots of steeps, if the weather permits them to open all the trails. Plus, there are plenty of intermediate blues all over the place. To avoid the crowds, get away from the lifts that are right next to the three lodges. Then you'll find some short lines. When there's a crowd on the mountain, stop along the side and do some people-watching while you catch your breath. Then go down when no one's coming.
And then there's Killington, of course. Do you really want to do that, just for longer runs? Check out why people avoid Killington in other threads.
For long runs, you can't beat Wildcat. Their summit is the highest, and their long runs are the longest in mileage, no arguments there. But, alas, they don't have much money for blowing snow so they are more dependent on the weather than some other places. No terrain park to speak of, thus few snowboarders (Yes!!!), but there are lots of people who have season passes or who buy the Sunday afternoon cheap lift tickets, so it does get crowded, and wind does blow the snow off some of the wide slopes. But they have lots of narrow slopes, and this year it's snowed a lot, so most of the trails are open and full of lovely snow.
But I'm not recommending Wildcat to you for a one-time-during-the-season-with-friends-vacation. Just know it's there if you're in the area. I love that mountain. It has the LONGEST runs in New England because the mountain is so tall; it's a 4,000 footer, and offers great views of Mt. Washington across the road and of Tuckerman's Ravine, and some people say they can see the skiers over there (do I need new glasses??? I sure can't see them!). If you are waiting till the last minute to make your choice, keep checking the trail reports at Wildcat. Their trail reports are honest, which is much more than I can say for any of the other resorts. Steeps at Wildcat, well, no. Bumps, well, really YES! (if it snows....) Old-style New England? Well, you can't get much more old style unless you go to some small tiny place like Black, or Mad River Glen. Some people will never, ever, go to Wildcat because its grooming is notoriously bad when the weather is warm-then-cold. Remember this!
One more push for Attitash.... for steeps, you can't beat Upper Ptarmigan, Middle Ptarmigan, Avenger, Kachina, Idiot's Option, Tim's Trauma, and Tightrope. These trails match any others in the East for steepness. But they are short, granted. (For long steeps, go to Killington or Sunday River.) Which means if you want a bail-out at Attitash, it's not too far down the hill. This year their grooming and snow-making matches anything Bretton Woods offers, and surpasses it. You'll be surprised.
