We were staying in Chalet Planai one week in New Year 2021. We stayed in an apartment for 10 persons, 2 families with 9 adults altogether.
Everything functioned very well, the apartment was furnished to give priority to staying together all of us - a huge open space area with kitchen, dining area, and sofa section, where we stayed most of the time all of us, eating, playing cards, hanging out etc. Bedrooms for all of us and two very nice and big bathrooms - one for each family :)
The chalet is situated in a great spot. A decent skier can easily walk a very short distance to the piste, running down to the lift station, taking you up to the top of Planai, and also it is easy to take a short drive by car to reach the great Planai area.
Overall the ski area is suitable for skiers of different levels. And you never get tired of the same pistes, as it is easy to reach Hochwurzen and Hauser Keibling nearby. We loved it, and will definitely come back.
