The largest ski resort in the world, without competition, is Les 3 Vallées in France with the major villages Val Thorens, Les Menuires, Meribel and Courchevel. Les 3 Vallées has 600 km of piste which no other linked ski area is close to.
Here is a list of the 10 largest linked (piste or lift) ski areas, their piste length in km, number of lifts, transport capacity per hour and country.
1. Les 3 Vallées 600 196 242.000 France
2. Paradiski 425 187 210.000 France
3. Via Lattea 400 78 110.000 Italy & France
4. Sella ronda 330 155 240.000 Italy, which is a part of Dolomiti Superski
5. Les Sybelles 310 71 80.000 France
6. 4 Vallées 300 64 65.000 Switzerland
7. Matterhorn ski paradise 300 58 99.500 Switzerland & Italy
8. Espace Killy 300 94 136.000 France
9. Avoriaz 270, 79, 100.000 France & Switzerland, which is part of Portes du Soleil
10. Skiwelt 263 91 138.000 Austria
Ski routes are not included in the table above. If these are included are the piste lengths: 4 Vallées 370 (incl the ski route connected La Tzoumaz sector), Matterhorn ski paradise 350 and Skiwelt 279 km.
A ski area can be defined in several ways, one is a number of lifts and slopes which are all interconnnected with each other without the need for a bus or car ride (as the list shown above). Another definition of a ski area would be a lift pass valid in several (or multiple) separate systems with a need for a bus or a car ride to get inbetween them.
A list for the latter definition would give the following lift passes:
1. Tirol Snow Card with 4000 km of piste in 86 ski regions (Skiwelt is part of this).
2. Salzburg super ski card with 2552 km of piste in 22 ski regions.
3. Dolomiti Superski with 1200 km of piste divided into about 30 separate systems (Sella ronda is part of this).
4. Kitzbuheler alpen all star card with 1088 km of piste in 12 different systems (Skiwelt is part of this).
Please note that all these 4 ski areas are geographically so spread out so there are several hours drive from one end to the other so you can not really make use of the entire region available for the ski pass.
More ski passes on this list would be Ski amadé with 860 km of piste (about 20 systems), the Zillertal Superskipass with 671 km of piste (7 systems) and Portes du Soleil with 650 km of piste (Avoriaz is part of this, 7 systems), all three of which are geographically within reasonable driving distance or bus interconnected.
The biggest ski area available on one ski pass within a 30 minutes drive from a suitable accomodation is probably the major parts of the Kitzbuheler alpen all star card. From St Johann in Tirol you can reach over 800 km of piste in 30 minutes by car (Schneewinkel, Skiwelt, Saalbach (via Leogang) and Kitzbuhel).
The Shrahe report that was published in autumn 2013 shows that most resorts exaggerate their piste length of up to 150%. The numbers above are taken from before that report. The austrian resort have generally adjusted their piste length down whereas most other have not adjusted their piste length or have simply taken away the piste length information. Adjusting the austrian numbers down while keeping the others would be unfare, especially since the austrians seems to have a smaller inflation factor than the others. So for now the old numbers remains.
If you want a longer list have a look at "What are the 50 largest ski resorts?"
The answer depends on what type of skiing/boarding you do. If you are looking for less crowded, steep terrain, go to Kirkwood, a fantastic resort and a locals favourite. If you want something that's close to all the hotels and the "city" go to Heavenly. Heavenly is a huge resort with something for everyone - in this respect it's probably the best, though it gets very crowded on weekends and holidays.
The best ski resort in Southern Vermont is Okemo. Central Vermont is Sugarbush, and Northern is Stowe. Killington is too big and you can get lost there. Stratton is too commercialized and crowded. Mount Snow is way too crowded. Smugglers Notch has terrible lifts. To me the best in Vermont is Okemo! The best all around:)

In my opinion, I would have to say Vale.
There are several ski resorts at Lake Tahoe. Alpine Meadows ski resorts is located on Alpine Meadows Road in Tahoe City. Heavenly Mountain ski resort can be found on Saddle Road in South Lake Tahoe. Kirkwood Mountain Ski resort is on Kirkwood Meadows Drive in Kirkwood. Mt. Rose ski resort is located on Mt. Rose Hwy in Reno. Northstar California is on Northstar Drive in Truckee. Sierra-at-Tahoe ski resort can be found on Sierra-at-Tahoe Road in Twin Bridges and finally, Squaw Valley ski resort is located on Squaw Valley Road in Olympic Valley.
The Heavenly Ski Resort is located at lake Tahoe near the California and Nevada border. Heavenly Ski Resort is one of the most popular winter ski resorts in the United States.
I'm thinking Kirkwood, after Squaw and Heavenly.
The Heavenly ski resort is a ski lodge that is located near the California and Nevada border relatively close to Tahoe Lake. There you can enjoy many winter activities.
