I'm not native to this forum, but I have spent a good amount of time scoping out the different resorts over the years and I'm not an advanced skier, so I might be able to contribute.
Stratton should have enough wide easy greens even from the top. As I recall, East and West Meadows are just as their names imply: wide and low angle. Also nice easy trails, not quite so wide open, from Tamarack on the lower 3rd of the mountain. In my experience, steeper trails tend to get scraped off quickly by crowds. Stratton also has the only real slopeside village in NE that I know of - a walking mall with shops, restaurants etc.
Okemo is a great fit for lower level skiers in general. Grooming is top notch and almost nothing is steep, so it's tough to get into trouble. Lots of wide greens and easy blues. While there are plenty of slopeside accommodations, there's no "village" as such. Ludlow has some pleasant lower priced overnight options.
Concur with Angus that Bretton Woods may be the best for lower level skiers, with lots of different green options and the bonus of an amazing view when you can see it. No village, but if you stay at the Mt. Washington (expensive of course), just about everything will be at hand. If you stay in North Conway, which has tons of accommodations at all different price levels, you can take a day at Wildcat. The trip down Polecat is a great experience for beginners.
Stowe is one of the few places I have not been, so I can't compare.
MLK weekend is likely to be both crowded and pricey at all the big resorts, so maybe some others can comment on ways to avoid or deal with the worst of that. Good Luck!
