rufus,
travelled in a large group with crystal about 3 years ago to France - their service was fine - no better no worse than expected (have been away with panorama before and they were rubbish - at least this crew know something about skiing) - the thing that gets me is the long transfer (invariably with a pointless stop in some hellhole (service station, tiny town with single loo etc.) and constant babble to buy lift passes, torchlit evenings, group drinks sessions etc. while imprisoned on same transfer - oh yes, and the ridiculously early start to the day of return (we left les arcs 7 hours before our flight - for a car journey that would have taken 2 at the most)
.... but Crystal do what it says on the packet - get you there, find your accom and get you home without any thought on your part so be happy about that
... advice would be to book the holiday and nothing else from them though - lessons, lift passes, excursions etc. can all be purchased cheaper at the resort with a little research ...
where are you going?
enjoy!
