Most of the resorts around Tahoe have some form of ski in/out, but the resort prices for accomodation are super high. Most resorts are close to hotels/motels though, and in South lake theres specific ski resort buses put on too to all the ski lifts onto Heavenly
Plenty of nightlife/Casinos in South lake & Stateline, lots in walking distance from major hotels and motels. We've stayed in low to mid-range motels mostly and run about $100-$120/night (Quality Inn/holiday inn/rodeway etc)
In South Lake youre pretty much limited to Heavenly (which isnt a bad thing!, its huge – you can ski for days and not take the same run twice) – Sierra at Tahoe about 30 mins drive and Kirkwood about 45 mins to an hour. North lake resorts all in excess of an hours drive (on a good day!)
North Lake Tahoe / Truckee area is generally quiter. Nighltife is not as bumping as South lake, but there is way more choice for skiing (imo). Ski in/out at Northstar resort (one of my favoirtes for boarding and nightlife, but ive never stayed there!) – All within half an hour of Truckee you have Squaw Valley, Apline Meadows, Northstar, homewood, Sugarbowl, and a few smaller resorts, most of which have base of slope accomodation. An hour out into Nevada is Mount Rose & Diamond Peak. Your only half an hours drive from Reno too for an intersting night out 😛 Plenty of cheaper hotels/motels in Truckee
despite the comment above, ive not yet found a major Tahoe resort that prohibits snowboarders.
Of the lot up there, Heavenly, Northstar and Squaw are my favourites. Heavenlys got a bit of everything, Northstars gots some great open runs and lots of trees with superb tree runs, and Squaw is a great big open bowl.
hope it helps (i used to spend 6-8 weekends a year in Tahoe when i lived in San Francisco so have a bit of local knowledge!)
