Well, you're going to find Tremblant much different than Blue. Tremblant is probably 5x the height of Blue and much more challenging. If you're up early, which is the best time, you'll be done by 3. Staying at the Sommet will get you first tracks. Best skiing of the day.
I am not a fan of Blue. In contrast to Tremblant, which has heavenly long runs, skiing at Blue always feels like work. I find the runs too steep and icy. I am very comfortable on black diamonds at Tremblant, but wouldn't even attempt them at Blue.
Really, really, really hoping to check out some Colorado resorts this winter!
