Hooch is correct.
In addition to the gondola (avoid peak times to miss long lines), there is a great free shuttle system along with the T-Ride city bus system. Not sure if they are going to run the shuttle to mountain village anymore.
To walk to town from Mountain Village is an 8-10 mile hike (the long way around) and much shorter/longer hike over the mountain following the trails of the gondola (few people walk all the way!
). Bikes are good for long haul as well.
Transportation is carefully manicured every year to optimize everyone's needs. You will find helpful people everywhere.
Have fun festivating!
