Kitz has some nice offerings, including a few areas of lift-accessible off-piste terrain. Unfortunately, the off-piste snow was of the mashed potatoes variety, so it was hard to enjoy it. For Spring skiing, the pistes were in pretty good shape. Lifts were modern and fast, and lines were almost non-existent. Didn't really sample the nightlife, but the town of Kirchberg looked very appealing.
My only complaint with Kitz would be the same as for most Austrian resorts...once you've been bitten by the bug of high mountain skiing in the French and Swiss alps, the mountains of Austria seem tame by comparison. The highest elevation at Kitz, 2000m, is lower than the mid-stations at Zermatt or Chamonix.
