Myself and two of my sisters are looking at hiring a holiday home to share for a week.
The one we like we have used before but it is really too big for this holiday. It has 7 bedrooms. They hoped some of their grown up kids could come and we have a school age child.
It's turned out that theirs can't come.
My sister's say the fairest way to split the cost is pay for the rooms we use and pay a third each for the four empty rooms. I said that is fair for the 7th room (split the cost) but surely we should all commit to pay for 2 rooms each.
The reason for this is none of us want or will use more than a third of the rooms but all will share the space. I'm not sure why I should pay more than a third of the cost given I'm not going to use more than a third of the space. If their kids were coming as hoped they would be paying for those rooms. If i or one of the others wanted more than 2 rooms we would pay for the third room.
Basically they've said "we don't want these rooms now so you've got to pay towards them. I'm like "hang on, I didn't want them, it's not my fault your kids aren't coming, we get a smaller house (if 4 bed I'd pay a half the cost or if a 5 bed I'll pay for two rooms and a third for the unused room as nobody can be wholly responsible for the odd rooms, but if 6 then we should again all pay a third and take responsibility for a third of the rooms each.
I'm not sure why I should pay towards what I see is their share of the house cost when I'm not using more than "my" two rooms?
It's caused a big argument as they say they always do it like that with friends but I pointed out their house shares never end up with as many or more spare/unused rooms than partners in the house share so this scenario never occurs.
