Best company for 5 night ski package?

As it is the biggest week for the U.K. ski market, combined with the fact that week long trips are more the norm and short breaks are not commonly offered. I think you'll taking whatever you can find.. unless you're talking 2018

Italy's smaller resorts would be a better bet than France I suspect. I'm not as familiar with Austria beyond the well known big hitters and doubt they would offer good value.

Having booked a few short breaks, we always found independent travel the better option. However transfers can be expensive.

Morzine has a very short transfer from Geneva airport(less than 2 hours), but I doubt in half-term you will find a short break easily. It is usually Saturday to Saturday stays only.

Private owners maybe more flexible. We don`t rent ourselves but have a place here in the four valleys. (direct train from Geneva airport to Sion)
