Mayrhofen is fantastic but the gondola up sucks
You obviously never used the old Cable Car! The "new" gondola is incredible by comparison
I lived in Mayrhofen for 10 years and I love it. The Zillertal ski area is massive and has some brilliant skiing. Mayrhofen town is a busy place, but there are plenty of options nearby if you want a bit quieter but still access the same ski area (as mentioned above) Hippach/Scwendau, Lannersbach/Eggalm, Finkenberg. All lovely villages with plenty happening but quieter than in town.
The zillertalbahn train from Mayhofen centre links to loads of other skiing down the valley really easily, as does the bus service, and it's all free (and no hassle)
Zell am Ziller down the road could be a good option, lovely skiing there and a great little town, Kaltenbach is much the same although slightly smaller, Fugen and Hoch Fugen also have brilliant skiing.
The area is large and varied and all available on one ski pass, well worth a look I reckon.
