Me and our large family planned to go on holiday this summer. This included my wife &amp; I and our 2 young children, my two sisters, my single brother and my other brother his girlfriend and their son. They recently announced that they are expecting a baby due slap bang in the middle of the week we are due to be away.

The total cost of the holiday is £1600 and my Mum has suggested that now they can't come away instead of it being split by 9 adults (£177 per adult) they shouldn't pay and we should split it by 7 adults (£230 per adult). This is way over the budget we initially set. Or alternatively they should pay their share of the deposit (£67 per adult) and we split the rest (£210). In both of these cases I feel the cost of the holiday is much higher than planned.

I personally think that they should have planned better and should still foot their share of the bill even though they can't come. AITA?
