Fantatic destination. Four of us spent three nights/two days skiing the weekend after President's Day. The mountain is huge, and that can't be overstated. By comparison, I skiied all day for two days at Snowshoe and never felt tired, while I was wiped after a couple of hours on the first day at Whiteface. Skiing from the summit to the base is a 20-30 minute trip, depending on how often you stop. Literally did not wait longer than 1 minute at any lift at any point over two days. Great variety of trails, although the greens are all segregated from the rest of the mountain (with one exception).
Conditions were pretty good. Got a couple of inches on our first day that generated some good bumps. The second day was a warmer and sunny. Some icy spots, especially on the lower third of the mountain where there were more people, but we are on the East Coast.
Lake Placid was fun (no more than 10 minutes to the mountain). Long single street with bars, restaurants, and shops. Many different options for food and atmosphere, although most of the tourists were back in their hotels by 10 pm. I'd recommend staying here as there's lots to do and there is no lodging on the mountain.
The resort itself is nothing special. The drop off area was crowded and the closer parking lots were $12-20, although there was a shuttle to the farthest parking lot. Workers were generally pleasant, although the rental area was not tightly run even though it wasn't very busy. Ate at the food shack at mid-mountain; if you want warm food and a drink, it'll cost at least $10. Nice area to sit outside overlooking the lower half of the mountain, including a fire pit.
I would highly recommend Whiteface as a skiing destination. Great skiing on a huge mountain with lots to do after.
