Another thing you can do is try to figure out local bus routes / shuttle systems to minimize expensive rental cars. I recently flew into EGE, got a rental car for 1 day ($57) to get to Frisco, and stayed at a hotel near the Transit Center. Used Summit Stage (free) to get to the ski areas. And when leaving, I took Bustang ($12) into Denver, and from there an Uber ($38) to the airport, after meeting some friends there overnight.
If I'd kept a 4WD car the whole time - which I don't bother with at Eagle - I think the rates I was looking at were $300-$400 based on time and a point to point surcharge.
Also I usually call up hotel desks and ask all the details for how the buses work in practicality. In February I went to Solitude/Brighton and picked the Hampton Inn BCC because the free bus (with Ikon) stopped in front, and as the front desk correctly noted, their stop is before the big car parking lots, so one can get a seat when it gets crowded. So I would suggest speaking with properties to find out everything you can.
yeah.. ski area buses are nice. We rented a car from Denver, dropped off stuff in Avon and returned the car in EGE, took uber back. I have a corp code that does not charge anything extra for one ways. Spent next 15 days skiing without a car. The cost of rental car would have been pretty close to the cost of epic pass for the trip.
