Am about to fly Thai Airways to Bali next week alone with my 6yo twins and have just discovered they don't have individual tv screens for the kids to choose their own movies etc. I feel like having a full blown panic attack! Flew with Virgin to South Africa 18 months ago and the fab in flight entertainment system was a life saver - I just assumed that all long haul airlines had those individual systems these days. So any top tips on portable DVD players with long battery life gratefully received. Friend has also suggested audio book on ipod idea. Have one ipod so that will keep one of them occupied for a while. Any other thoughts?
