Another splitting costs with family

[Bananapants5]

Weekend trip with family

Parents (pensioners)
Sibling 1 - with husband and 2 children (young)
Sibling 2 - with husband - teen children not interested in coming.

Wanting to book 4 bed place due to ages of sibling 1s children
How should cost be split?

Split into 8 and then each family pay cost? (YABU)
Split among 6 adults? (YANBU)

To not drip feed the cost of 4 bed place is no more than a 3 bed place

Split 7 ways with sibling 1 paying 3/7.

1/3 each

When we have gone away with friends in circumstances like this, we have split it as adults pay full price and kids 50%. The kids will be using all the living spaces as well so it's only fair the family with kids contributes more. This worked whether families had one kid or three.

We used this system in many different locations, so sometimes those with kids had bigger rooms and their kids were in with them. In other places kids got their own room, which tended to tbe the smallest room. But families with kids always had more space overall

Split per room. It's a red herring that you could get a 3 bed for the same cost. The communal areas might be much nicer in the 3 bed, or there might be an extra bathroom.

We have this set up coming up. I'm sibling 1. I covered to pay for 1/2 as we have 2 bedrooms but sibling 2 and parents have said no and we are all paying a third. To make it fairer they will be getting the nicer rooms and the 2 we have aren't as big/nice. So it depends on your family dynamica

Parents (pensioners)
Sibling 1 - with husband and 2 children (young)
Sibling 2 - with husband - teen children not interested in coming.

So -

Parents pay one-quarter
Sibling 1 pays half (two rooms & twice as many people using the bathroom etc)
Sibling 2 pays one quarter.

Tell us you're the sibling with young kids without telling us op.

Nooo, surely the parents of disinterested teens. You can't pay according to level of interest.

1/3rd each per couple. Sibling 1 gets last choice of their 2 rooms, although could be tricky if not close together/ on separate floors.

I would chip in a bit more if my kids had their won room

🤣🤣🤣 I am not

Split into 3.

Usually rooms are not equal.

I mainly want it to be fair for the parents tbh, it won’t become a bone of contention because we aren’t great communicators so wouldn’t know but potentially it would be brought up if we were to do a similar thing again.
Sibling 1 is quite keen to have her children involved in family things like this where sibling 2 wasn’t

I am the parent of the teens, they are staying at home however so don’t need paying for

You split it between the couples ; 1/3. If 4 rooms were much more expensive than 3 I would have said to pay per room as on sibling with children covering half the cost of the total. This is not the case so it's very easy to settle at 1/3. Why, are you not happy with that OP? Do you think your sibling should pay more just because they use two rooms?

I’ve not said anywhere that I’m not happy with that.

Treat the 2 kids as half an adult each if under 12 y o?

If you do only the adults pay, it sets a precedent, and they might be big strapping teenagers on subsequent trips.

Well, you came here to ask so I take it wasn't obvious in your mind to split 1/3?

If I were the parents of the 2 children, I would offer to split per room purely because out of principle of my family having an extra room. I guess the reality is there is an extra room in the house which no one else can use if it is being occupied by these two kids.

If I were the sibling with no kids on the trip and the cost was genuinely the same as the 3 bed, I'd say don't worry, we would just split it 3 ways.

In this scenario we split by bedroom. It’s irrelevant what the cost of a 3 bed place is as presumably it doesn’t have enough bedrooms.

How about my suggestion of 1/7’s and sibling 1 pays 3/7?

I guess that’s what happens when you assume things.

How much is the difference in splitting it 3 ways rather than 4

In all honestly, these things only work if the parents pay the lot. Otherwise it descends into petty resentment because X got the room with the ensuite and Y used more than their fair share of cornflakes.

This is the silliest answer
