Two of my nephews received a 'Ski Fun Taster' session as a Christmas present and as one of them was under 10, needed an accompanying adult. Uncle got the short straw.
They advise you to arrive in plenty of time to sort out your ski boots and get your skis fitted, so once we'd checked in at the reception desk we were instructed to head over to the equipment hire place and everything was arranged efficiently. There are lockers to keep your belongings (bring a pound coin with you).
The rest of the adults in our group promptly headed to the upper level to get a decent view of the slope (i.e. get a drink at the bar / prep the camera phones so they could video us falling over).
There were 10 of us, of all ages, in the session with one instructor who first spent some time teaching everyone about the different parts of the skis and other basics.
Then it was on to the training slope - it's only a slight gradient and not on the main slope so you won't need to worry about other skiers whizzing past you or have to get on any drag lifts.
For the rest of the session, the instructor gave us a few different basic movements to do whilst we slowly skied down one-by-one, allowing everyone to get used to balancing with two planks of fibre glass under your feet :)
The boys loved it, even though one of them was rather hesitant at first and the other continually fell over as we had to side step up the slope with our skis on.
As it was only a Taster session, it was obviously very basic to introduce complete newbies to skiing. I've got a feeling they'll both be wanting Beginners lessons after this!
