If you like skiing, Paragon Sports (18th street & Broadway ) offers a very comfortable one-day trip. Visit Paragon Sports and they will give you the best option.
Bad news is you will have to wake up a little early (meeting time 6.00 AM) but you will be skiing by 9.00 AM. Return time is at around 4.30PM.
You can also rent your equipment with them for a very reasonable price. It is instructed to visit the shop at least 24h before the departure date and they will have all the equipment ready for you on the day of the trip.
Enjoy the trails!
