Senior Year Ski Trip

Me and some of my friends from college are planning on a colorado ski trip this winter. We’re thinking about planning a Colorado trip for 4–5 of us, staying around 4 nights and 5 days. The plan is to ski or snowboard for at least 1–2 days. We’re looking at staying in a hotel in Boulder so we can go to Eldora since it’s the closest and relatively affordable, unless anyone has better recommendations. Nothing is set in stone yet, so if there is better deals somewhere, or just overall better for the money then Im open to hear it. We’re planning to buy or borrow our own gear—jackets, pants, boots, boards or skis—before we go in December. Any tips from locals or regular skiers to save money and make the most of the trip for a group of college students? How much do you think this trip would cost? Hopefully this actually makes it out of the group chat.
