I am planning on going on a snowboarding trip to Utah in mid-late
March. I was wondering if anyone knows of any cheap loadging/lift
ticket combo (or separate) deals from Salt lake city? I have heard of
superpass.

The Superpass is a combination lift/ski bus voucher for any one of the
Cottonwood Canyon resorts (Alta, Snowbird, Brighton, Solitude) which
can be bought at many of the hotels. You turn it in at the ticket
window of the resort, and get a "real" pass. I stayed at a Best
Western, and they had the passes for the four canyon resorts. It was
$50, and was a good deal - even includes the tram at Snowbird.

The ski bus is pretty cool, and access able. A big benefit of the bus
- the Cottonwood Canyon roads are often restricted to vehicles with
chains or 4WD. If you are up there with a 2WD, you might be SOL when
trying to get back to your motel. The ski busses run unless the road
is closed to all traffic. SLC also has great "around town" public
transportation that you can use to head downtown to see Temple Square
or other sights.
