Utah has many great places to ski. There should be good enough snow around Christmas but that is upto higher authorities!
The places with pure ski-in/ski-out in Utah that I know of:
Deer Valley is a great place to ski, long, broad runs, many of them are groomed, good place for family, but it also is the most expensive generally - but not completely. Alta is a great place to ski with kids but its definitely harder, not as much grooming. Snowbird is also a great mountain but generally steeper as per experts. Finally Solitude is quite nice, smaller than the three above but quieter and there is Brighton right around the corner. All four of these places have pure ski-in/ski-out accommodations (we prefer that too, my son and I) and I would say on the whole Deer Valley would generally be the most expensive, then Alta, though the lodges include breakfast and dinner in Alta in the room charge, then Solitude(condos or Inn at Solitude) and finally Snowbird, especially since at Snowbird there are often deals to be found.
We know Deer Valley, Alta and Solitude well, and to enjoy Alta, and Solitude, famous for powder, that's what they are famous for and also for creativity, i.e. making your own ski trails, whereas Deer Valley is more organized, and for the middle-aged intermediate Dad, its quite good, especially when steep runs are groomed! Snowbird is also powder-country and is definitely steeper all around, if folks are beginners to low-intermediates, I would have to lean towards Deer Valley, then Solitude(its a bit smaller than Alta, or Snowbird or DV, or felt that way, nice purpose built-village though, car-free, and great kids club for all visitors, so apres-ski, kids can have a blast!) and then Alta (Alta lodge has a great kids program post skiing, we stayed there twice in 2010!), and finally Snowbird, but really to enjoy Snowbird or Alta, one's skiing has to be pretty good. Alta is known for its traverses, all true.
Enjoy, all nice and all 4 have ski-in/ski out.
Comments on Lodging:
1. Deer Valley, Goldener Hirsch Inn: Great place, great staff, management, very good food, Austrian style
2. Inn at Solitude: Young staff, enthusiastic, Kids club very popular with my son.
3. Alta Lodge: Excellent, great staff, great for kids and just an old-world, classic experience.
There is also Park City Mtn Resort and the Canyons, but have not skiied there.
Look on the site, do a search, others have reviewed and look via search function, there are wikis on them too I think.
