Enjoy Ski has contracts with:
ski schools;
instructors speaking different languages;
personnel speaking different languages.
If you plan book a ride with an ski-instructor for the period of ski holidays you should take care of booking as soon as possible.
So, for the Christmas or New Year period it is recommended to book instructors in August or no later than September. If you start to book the time of riding just before the trip, you have risk to have being left without individual lessons. It is also worth bearing in mind that the schedule of weekends and holidays in your country and abroad may not coincide.
