mate if the conditions look bad at least go and jump on the gondala or the 4 man at yesterbets. Best 2 days we have had we had already written off then found out it keep most off the slopes leaving them for us to play on. Yesterbets 3 has loads of natural kickers and areas to mess about.
If you don't mind a little yump their are loads of tree runs on the top of the moutain. Just keep the piste in sight.
Plenty to do and have fun.
