Alright i have some weird suggestions and some not so weird ones.
weird ones first ok: Black and magic mountain NH and VT respectively these places are where skiing has its soul they dont have parks and only a slow ass double to the top but seriously these mountains are so fucking cool. glades steeps and good vibes is what fuels these places (pretty cheap day passes too also both on the indy pass)
Another Indy mountain is Saddleback all the way up in rangeley Maine, some of the steepest steeps in the east and a shit ton of glades. they have a park with its own rope tow for sessioning and wide open groomers for carving or straightlining whatever floats your boat
Of course there is Cannon pretty extensive park gnarly glades and some steep hot lappable runs. Cannon is awesome.
Mount snow has a huge park with multiple trails and its own lift to service it
Then there is the huge stuff like sugarloaf and killington if you want big resort
