Hiya, Never been on Mark Warner holiday but have had some great breaks with Neilson in the sun and snow. We were actually away with them last summer when a family we made friends with (read laughed at each others windsurfing skills and drunk wine with) suggested a ski break - we were all total novices... still are really but it was lots of fun
We went as a bit of a motley crew of family, kids and friends and across the board everyone had a great time. Snow angels all round!
Would love to be going again this year but something something mother-in-law something something!
Worth checking out as another option and they seem to have some nice family type offers at the mo. *getting jealous* Lots of info on this page of the Neilson website:

Hope it's useful
Have a lovely holiday x
