Indy Pass gives you two days at Pats Peak, Cannon, Waterville, and a bunch of other mountains in VT and ME, as well as Berkshire East in MA. Two days at each mountain lets you explore and gives your kids experience at a range of places. Definitely a good deal if you're willing to not have a 'home' mountain. Just look into blackout dates depending on which pass you get. Also check out r/icecoast for more specific info.
