To think my sibling is being totally unreasonable about sleeping arrangements on this trip?

Posting here for traffic because I need to know if I’m being mad or if my sibling is just being ridiculous.

We (me, DH, DCs, my sibling, and their DP) are going on a family trip soon. It’s been planned for ages, all agreed and booked. We’re staying in a big Airbnb-type place with multiple bedrooms. The plan was that DH and I would have one room, DCs in another, and my sibling and their DP in the third. There’s also a small box room with a single bed, which was just going to be a spare in case anyone needed it.

Now, sibling has suddenly decided that they don’t want to share a room with their DP because “they sleep badly together” (which is apparently news to everyone, including DP!). They’ve said they’ll be taking the box room instead, which means DP will now have to share with one of my DCs (who is 6 and not thrilled at the idea of sharing with an adult they barely know that well).

I told them that’s not fair and that they need to just suck it up and share with their DP as planned. They’re now saying I’m being unreasonable and need to be more flexible, and that the sleeping arrangements aren’t set in stone. But surely you don’t just unilaterally change things like this last minute?!

DM has now waded in and is backing sibling, saying I’m being selfish and that we should “find a compromise” (but what compromise? DH and I aren’t going to split up for the sake of their random issue).

So, AIBU to think my sibling is being totally unfair and should just stick to the original plan? Or am I missing something here?

TL;DR: Sibling suddenly refusing to share with their DP on a trip, wants to take the spare room, leaving their DP to bunk with my child. I’ve said no, now I’m the bad guy. Who’s BU here?

This thread is like an 11+ question and is hurting my head.

FOJN · 12/02/2025 20:39

I wonder if OP has had her "oh" moment yet?

RadStag · 12/02/2025 20:39

Sahara123 · 12/02/2025 20:38

🤔 ummm nope I STILL DON’T GET IT !!
22 pages of complete madness and we’re none the wiser

Because op wants there to be an empty room ...

Catza · 12/02/2025 20:39

RadStag · 12/02/2025 20:33

I think I actually understand what OP means ...

She is assuming/insisting that there has to ALWAYS be a spare room.

Say Sister and BIL in a double room. Leaving box room spare

So by sister moving into single room, this means that BIL "obviously" has to move out of the double room, to ensure a spare room.

So he has no bed. Hence sharing.

So he would only have the option to share OPs room OR the kids room, naturally (?) OP is assuming he has to share with her kids 🤷‍♀️

i know, there's no need for the spare room

Edited

Not her kids, just one kid. But let's not get into the mystery of what happened to the other as it requires another large glass of wine.

Sahara123 · 12/02/2025 20:39

So she wants to leave a double room as a spare ? That’s actual nuts

HMW1906 · 12/02/2025 20:40

I don’t get it! There’s 4 bedrooms why does partner have to shear with child????

bedroom 1 - OP/DH
bedroom 2 - child
bedroom 3 - sisters partner
bedroom 4 (the spare box room) - sister

i don’t really understand what the issue is.

ClemmyTine · 12/02/2025 20:40

Blanketenvy · 12/02/2025 20:38

But she says the box room has a single bed...

Oh yes, I'd forgot. :!

ThatGreatMember · 12/02/2025 20:40

PandaTime · 12/02/2025 19:36

But where is the other DC supposed to sleep if DP takes their spot in the bed beside the 6 year old??

This! I was thinking exactly the same.

menopausalfart · 12/02/2025 20:41

What happened to the original bedroom your DS and her partner were sharing?

Soitwillbefine · 12/02/2025 20:41

As many have said above, you said the room allocation was one for you and DH, one for sibling and partner, one for your DCs. Small room vacant.

It sounds like you’d mentally earmarked the spare bedroom for you and your family and are now a bit peeved that your sibling has said they’d like to use it.

I’ve absolutely no idea why their DP would be expected to share a room with one of your kids! Surely if that was to come about it would be better for your sibling to share with a niece or nephew. You’ve not made that clear.

Mountains and molehills!!!

Grinchybinchy · 12/02/2025 20:41

My god I skipped 23 pages and even with the most up to date posts nobody’s none the wiser 😂

EveryOtherNameTaken · 12/02/2025 20:41

Jeez. This nuts. Do you also get a spare room if you stay in a hotel?

LilacLilias · 12/02/2025 20:41

ThatGreatMember · 12/02/2025 20:40

This! I was thinking exactly the same.

There could be more beds in the DC room than just the bunks. There could have been a spare bed space. Although therefore aren't any other DC inconvenienced? Are we sure there are more than one DC

I think you must be right.

Your explanation makes perfect sense.

Now what obviously does not make sense is...
WHY the need for an empty bedroom at all time? This is what has been hurting my brain 😂

The OP could share with the BIL?
Her partner share with their kids?
There are ways to muddle that even more?

What about sharing with the air BnB next door?

Tohaveandtohold · 12/02/2025 20:42

I don’t want to believe the op is real, like how hard is it to grasp. The only person I feel sorry for is your sibling who’ll be stuck on holiday with you.

scoobysnaxx · 12/02/2025 20:42

OP has just done this deliberately to cause a scene and watch it kick off. Just let the thread die..

Gingerbiscuitt · 12/02/2025 20:42

jd206 · 12/02/2025 19:34

I get what you’re saying, but the issue is that my sibling has decided they must have the spare room to themselves, which means their DP is the one left without a bed. The only other option is for DP to share with one of my DCs, which obviously isn’t ideal!

If sibling had flagged this earlier, we could have worked out a better arrangement, but changing it last minute just puts everyone in an awkward position. I don’t see why my DC should have to accommodate their sudden preference not to share with their own DP!

Bedroom 1 - You and DP
Bedroom 2 - Children
Bedroom 3 - Sister and DP
Bedroom 4 box room - Either empty or your sister is in there

I really don't understand why your DP will have to share with the children if your sister has the empty bedroom??

You don't make any sense.

menopausalfart · 12/02/2025 20:42

You sound like a control freak.

at least posters have made it really funny 😂

and politically correct, this thread is a winner

LilacLilias · 12/02/2025 20:43

menopausalfart · 12/02/2025 20:42

You sound like a control freak.

But you see they had all agreed there would be a spare room and everyone was sharing appropriately

Fizbosshoes · 12/02/2025 20:44

Where is @jd206 ?

OP I really hope the diagram you're obviously working on, is really good....!

TitsInAbsentia · 12/02/2025 20:44

Pleaseletmegohome · 12/02/2025 20:27

I do so feel for the late joiners.

I don't...I'm only staying here just to see people trying to make logic out of somewhere that logic is never ever going to visit...unless it gets the 'spare' room of course 😂

Endofyear · 12/02/2025 20:44

This makes no sense! DC are sharing a room so your sister and DP sleeping separately would make no difference? Why on earth would your 6 year old have to share a room with sister's DP? That's batshit crazy!

BobbyBiscuits · 12/02/2025 20:44

The box room was going to be a "spare" but instead it's being slept in by someone.
Why does it mean you or your family have to swap? It just means the husband of the two of them will have a big bed to himself.

FcukTheDay · 12/02/2025 20:44

How about everyone just sleeps outside? There will be 4 spare bedrooms. Perfect 👌
