Replying to Coming out to utah and need some help

Well my family decided to go on a trip out to utah for a week and we are staying at a resort at the canyons.  My problem is that I have wanted to ski Alta/Snowbird but im just not sure if they will let me take the rental car out to lcc.  How good is the terrain at the canyons?  I know they have a good park but im going to Breck for a week after so I wanna ski some pow, trees, and cliffs and that is it.  We will also be skiing pc maybe and I have a friend living in solitude so I may head over there.  Thanks/ + karma for any suggestions.  Also, we are going from december 28th to january 1st
