After travelling to Whislter in similar style, a limo seemed to be the only way to go to get to Breckenridge. The funny thing is that it doesn't cost that much more than getting a taxi, so why not travel in style. I could highly recomend the company that took us (Front Range Limos:
www.denvercoloradolimousine.com), as they were the cheapest and it came with a free, yes free bar.
