Don't really do tour operators these days as the internet has made DIY so much easier.
But here's a few thoughts.
1. Virgin (to
Heavenly - excellent service)
2. Crystal (to
Fernie in Canada twice - not bad at all)
3. Ski World (to
Courchevel 1850 - end of season, nine parts useless!)
4. Ski World (to Le Menuires and
Saalbach Hinterglemm - much better!)
5. Inghams (to Saas Fee three times, very efficient!)
6. Mark Warner (to Kitzbuhel and St Anton, quality all the way)
7. Erna Low (
La Plagne apartments, not bad at all)
8. Crystal (late deal to valmorel, much cheapness for best hotel in village)
Loads of others I've forgotten but probably the very worst was the late and unlamented Horizon. Went to Kitzbuhel where the rep thought the flight being cancelled and arriving in the hotel at 4am (12 hours late) to find it locked and no-one about was (cue camp rep accent) "all part of the holiday fun". He almost got a smack on the nose.
Ian Wickham: I remember going to Austria with Swans in 1975; does anyone remember Ski Plan (Sauze 1973!)?
