Replying to Senior ski trip

So I want to organize a senior ski trip this year at my school but it won't be done through my school. I want to either get everyone to go to killington on mont tremblant for a weekend but any other resort in vermont will do except for mount snow because I want a little bit better terrain. So does anyone know of any sites that do spring break style trips such as gradcity.com but they have packages to places like tremblant or killington?
