Good selection of hotels and eateries apres bars extremely busy and you struggle to get served. We stayed hotel Strass right next door to Penkenbahn I would advice requesting a room away from the attached Icebar if you like piece and quiet
The Penken lift first thing is a nightmare so get there early, first few chairs are also busy along with slopes, being a town with high cliffs all around you are limited to this one lift or Ahornbahn a ten minute walk away but pistes a limited at Ahorn (good black to resort) a couple of trips to the Hintertux glacier is well the effort as is a trip do to Zell Ziller lots of skiing there but just make sure your on Zillertal side of valley before lifts close or I guess it would be expensive taxi back
All in all a very busy resort I wouldnt rush back but I would go back at some point
