Howdy neighbor. We own at Poly and love it there.
You're a 3 min walk to the EPCOT monorail so in my view, Poly is both a near-MK and near-EPCOT resort.
And in both of those parks when kids are little, park to room can be done while they're sleeping in stroller. Can't underestimate the value of that.
Plus. It's the Poly.
