We are organising a large family holiday - with my Husbands three siblings and his parents. There will be 9 adults and 11 children in total. We have agreed to book a large villa and all split paying for DHs parents so we have suggested we split the rest four way by sibling.
However DHs sister believes this to be unfair as she is just one adult - but she has 3 children. Everyone else is fine with this arrangement as the family sizes go from 3 to 6 anyway.
Is this unfair my DH worked it out and it would cost her more if we were to pay per head however she thinks children usually go on holiday for free...
