1. Book your lift passes online in advance
2. Taking morning & afternoon snacks with you such as cereal, chocolate bars & dried fruit keeps you going for longer and saves on cafe stops.
3. Treat yourself to the 'plat du jour' aka plate of the day - a hearty, good value lunch option in the mountain restaurants. And help yourself to free mountain tap water.
4. Visit the InterMarche at the bottom of the valley - they have a great variety of food and drink. However supermarkets in Thonon are cheaper still. Group evening meals in the chalet are good value and great fun.
5. Use walkie talkies whilst on the slopes to minimize your mobile phone bill. (and don't forget to turn off your roaming!)
