The people that love Deer Valley are the people that a) want to sit around and eat and just look like they are skiers or b) think they're skiers but don't want to find out their not. The resort is groomed beyond logic. By day's end every groomer is icy and treacherous. The blues from the top of Bald Mountain are packed with skiers that think they're better than they are who don't have the skills to be skiing that fast. I felt like a defensive lineman trying to avoid a pummeling from Joe Blow in his Bogner suit. The off-piste terrain isn't bad except the runs are SHORT. The vertical advertised is misleading. You can't ski top to bottom. You have to ride a ton of chairs and download just to get back to your car.
You can get some vertical over in Empire Canyon but it takes an hour to get there and you'll have to navigate crowded and icy cattracks along the way. One other thing, the kids school is a joke on the holidays. 12 kids to a group??? It's their way of coercing you into giving your child a high-priced private lesson with some young foreign instructor who's no more experienced than your average babysitter.
I guess people rave at this place because they've never had a 'ski valet' help them with their skis or a liftie hold the chair so it doesn't whack you in the back of your knees. They take a couple of runs then go in for lunch. Anyone who is a core skier is going to say BTDT and head to PCMR or Snowbird after one day.
