Flying into a way busier airport, renting a car, sitting on I-70 for four hours to pay for parking or do a long walk with kids and equipment (or wait in line to rent) sounds way more miserable than going to a nice, small VT resort like Bolton or Smugg's. Even Stowe the only traffic is the last 5-6 miles on busy days and with two parents and two kids it's free parking even with the changes there. Obviously there are other western resorts outside of the greater Denver area (not even sure they qualify as Greater Denver haha, 1.5 hours on I-70 with clear roads and no traffic), but most of them are equally far from the airport and have similar traffic/transportation problems.
