Replying to Boulder

Hi, in January my dad is bringing me and a friend with him to boulder so while he works we will be able to ski big mountains cause we are from Quebec. First, I want to know if Eldora will have an okay park cause since my dad will be working he wont be able to bring us and I think this is the only mountain we can go by bus from Boulder?? Also I will be able to go ski at Breck or Key for one day so I wanted to know which mountain would be more fun for me to ski ski since in Qc I only ski small jumps and mostly rails. For the none ski activities is there a nice place I could go jumps on big tramps and other fun stuff to do in Boulder? and btw I am only 19 so bars are not an option in none ski activities.. Thanks
