I can't speak to what makes it worth it for you, but my wife and I went to GP for 3 hrs today on our season passes. They had Iliad, Elysian/Stoic, the top of Alcemene, Castor & Alpha open today. Looked like every snowgun they have was fired up and you could find edgeable snow on every trail. No lines at the lifts. Occasional lake effect squalls alternated with sunshine. For the recent weather we've had, it wasn't bad, but I wouldn't mistake it for an epic day
