WIBU to split cost of holiday four ways?

110 replies

Eldermilleniallyogii · 09/03/2025 20:59

3 adults and 1 child (age 3) going on holiday. Holiday package will not give clear split of cost. Mother and daughter will share one room. Younger daughter will share with her DC3. Would you just split the cost of the holiday four ways? They have a room each so makes sense to split the accommodation costs equally and the child will also need a seat on the plane but we had thought the child place might have been cheaper than an adult space.

Splitting four ways seems fair however will mean in practice A and B will each pay a quarter of the cost while C will pay half as she is paying for C and D but it is her child.

How would you split the cost?

Is there a better way to do this?

I think splitting four ways probably is fair if I can't work out the actual flight costs

Maybe your mum/sister will offer to pay a bit more.

DoYouReally · 09/03/2025 21:18

As the 3 year doesn't have an income source and is related to all 3 adults, splitting 3 ways is very fair.

I can't imagine charging my sibling for a 3 year old.

EasterIssland · 09/03/2025 21:20

Can you check how much would it cost 3 adults only ? And then 3+1 and the difference might be of the child.

abc 1000
abcd 1200

so the child is 200 and each person is around 340.

tho when I travel I tend to ignore my sons price and we divide bt adults rather than by people

Officenoticeofthisissue · 09/03/2025 21:21

When I go on holiday with my parent and two dc we divide by 4 because as a single parent I'd pay adult fare for the first child anyway (and also I feel that I don't want to cause issues with parent).

I don't understand this

It's a shame you are the one organising as if your sister was doing it, it would give her a chance to offer to skew it in your favour. You can't do that for yourself! Is there a big income disparity? Sister might feel annoyed at being asked to subsidise your child if she's struggling. IME most grandparents would happily subsidised grandchildren but sometimes to their financial detriment. I think the characters involved come into this a bit.

DorothyStorm · 09/03/2025 21:29

Im taking a child-relative on holiday and someone else is paying their costs. So i ran the numbers on the website with and without him to work out what extra he costs us. The same as an adult. So for us it would be split four ways.

m00rfarm · 09/03/2025 21:30

If two adults are sharing a room they pay for that room. If a mother and her child share a room, then they pay for that room. THe flights are pretty much the same for adults and children. I would pay for your child as being the fourth person. They are taking a seat on the plane and a bed as if they were an adult.

Is it an apartment or two hotel rooms?

2 Hotel rooms... you pay per room.

Apartment.... split between adults.
Flights... everyone pay their own (you can look up flights costs)

This!!

Bs0u416d · 09/03/2025 21:39

If it's your 3 year old and you're happy with an effective 4 way split then that seems most fair to me. However, if you were my sister and you asked, it suggest a 3 way split so maybe ask your DM and DS what they want to do?

thewashingneverends · 09/03/2025 21:39

Eldermilleniallyogii · 09/03/2025 21:15

It is an apartment

The accommodation price will be a unit price not per person and the flight cost you can gauge an idea checking flight only but the 3 year old is usually a wee bit cheaper x

bigfacthunter · 09/03/2025 21:48

My friends and I don’t count small children in group bookings so in this situation it would be a 3 way split for us. I personally think it’s the decent thing to do given that small children don’t earn money and parents of small children are often earning a lot less than they usually might.

I’d say just ask your family members how they’d like to split it. Hopefully you’re all on the same (or similar) page.

Nofrogslegs · 09/03/2025 21:49

If you’ve booked the flights and accommodation separately just price the flights again for you and dc then the difference between that and your actual flight booking is split between your dm and dsis.
accommodation wise I think you do need to split per room, ie you pay half and the other 2 adults pay a quarter each. It’s not fair to expect them to pay more just because you obviously have to pay your dc share. Really you have your own room (with dc), they don’t.

I think you’re right. There’s no way the little one should be cheaper: easyJet flights are a flat rate per person, no child price; and you should pay the full cost of the room you’re both using. To suggest otherwise is to suggest your family members subsidise your child which seems very wrong unless offered unequivocally by, say, a parent, well in advance. Which they clearly haven’t.

Whatdafudge · 09/03/2025 22:05

I mean if I were your sister I would just split it 3 ways between adults as you are family and that’s my niece/ nephew. Unless of course you have a much higher income compared to your mum and sister, and then I would expect you as the loaded sister not to want your family to cover something you can easily pay. Just talk to them about it - explain as you have here there’s no breakdown - what do you think is fair, I’m happy to cover whatever you think the baby’s cost would be X

HoldYourHat · 09/03/2025 22:08

I think split between adults only. A 3 year old doesn’t eat or use facilities like a teen or an adult.

We are going on holiday with family and splitting equally among the adults and there is one kid, a toddler (mine and DH’s), and I think that’s generous of everyone not to count our DC as an adult. The kid will sleep in our room.

CornishDew · 09/03/2025 22:10

If it’s one apartment as mentioned above, I’d price it as 3 adults and split this amount 3 ways. The difference from 3 to 4 being the child cost that the parent of the young child pays

CandidGreenSquid · 09/03/2025 22:11

If it’s an easyJet package holiday, it will tell you whether or not you have a free child place. Does it say this when you go to book? If so, I’d say the price should be split between 3 adults. If it doesn’t say you’re getting a free child place then you’ll probably need to pay for yourself and your DC.

Eldermilleniallyogii · 09/03/2025 21:08

Yes ABC and are adults 40+ and there is a three year old.

So as not to drip feed too much I am C and it is my DC who is three. I'm booking the holiday so not sure what to propose for the costing. It does seem off for the 3yo to cost the same but we will have a room to share and I don't know how easyJet prices child places on flights.

Ask the holiday company for the breakdown. For AI often the kids eat free.

Or split it 30/30/40 .

But it’s self catering, so no food. The cost is purely for the flights and apartment at this stage. All 4 people will use apartment equally, ie bed each, bathroom.

fatgirlswims · 09/03/2025 22:17

What's the total price? (Ballpark) Is everyone skint or comfortable

If it's wasn't £1000s and more along the lines of a week in Majorca I'd be happy to lay a few extra quid to spend time With family. If it was my grand child I'd offer to pay.

I think 40% for the adult and child and 30% each for adult is fine.

This is roughly the same as 7ths rule

Derbee · 09/03/2025 22:18

Divide by 7?

Both adults pay 2/7 each,
mum pays 2/7 plus 1/7 for the child

She doesn’t have her own room and will barely eat anything., split 3 ways and buy a lunch
