Yep, you nailed it, the Epic Pass. With a wife and 2 kids it works out economically. Plus, my in-laws have a timeshare on the Canyons side.
Brighton and Snowbird are 2 places I wanted to try but then Hilton opened the Sunrise Lodge and lodging for free makes the location decision easier.
Last year at Detroit Metro Airport I ran into Louie Vito (sporting an Ohio Against The World hoodie), who was flying back to Utah on the same flight. He told me he has a home on/near Snowbird and spoke very highly of it. I misinterpreted that as an invitation to ride with him, which he cleared up really quickly... lol... Actually, he was a cool dude and talked a lot more than I thought he would.
