I didn't realise that they hire out players. It will probably be worth getting one as at least one of us will probably want to watch it (ther will be 5 of us). And how could I forget about travel games I used to love playing these as well and im sure my older boys will as well. Ill def have a look around for some cheap travel games

both of these suggestions sound great as like I say my 2 older boys don't want to take their tablets psp etc as they are worried they will get lost or broken (they took them last year) and they both love playing board games and watching films so will def do both of these. The thought of a 4 hour flight with 3 bored children isn good not to mention a bored husband as well
We will be taking little toys and a book or two for my youngest (2 and a half) but the older ones seem slightly harder to please as (especially my eldest who will be 12) he is kind of passed playing with toys but loves sitting next to the window but that will only entertain for short periods during the flight.
