This comes up about once a year..somewhere there is a good thread about one poster who ignored the good advice about avoiding snowbird if your are a beginner (or even if you are a true intermediate) and he had a terrible time.
All I can tell you is to please heed the stern warnings and you'll have a much better vacation.
Now, if you want the best advice, here it is---for a beginning skier going to utah you will learn to really fall in love with the sport if you spend your three days at Deer Valley. Honest...yes, it is way more expensive, but if you are not a very athletic intermediate or better, the Little and Big Cottonwood ski areas aren't that great (yes, I know, Alta has some pleasant beginner and intermediate terrain...but that is no reason to go to Alta! Solitude is very pleasant as well, but again, for the advancing beginner, DV is way better). And, Park City is a great place to vacation in.
Most folks are too cool for school and will sneer at Deer Valley because it's posh and pleasant (and snowboard free)...But for an advanced beginner looking for a great three days on snow in Utah, DV delivers. And, It really delivers on the vacation part of a ski vacation!
Great instructors there as well.
Bang! That's it. The thread is over. Seriously if you want to have fun as a beginner in UT DV is the best place to go. Forget about powder (you will hate it) forgetable challenging terrain (you don't want it).
