We went to Ty Nadan last year - 2 x 11 year olds, really enjoyed it - lots of activitys & the staff are professional & friendly. We booked a 3 bed mobile & it was fine but I'd go for the chalet next time - more space around them & in better location's. Note: the campsite is inland & fairly remote - not within walking distance of a town. We're off to Le fief this year
