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

jd206 · 12/02/2025 18:45

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?

Why can't you and your sibling's DP sleep in a triangular tent at the western end of the garden? Then the living room will be free to be used as a living room, except you can't sit on the sofa.

I heard the llamas were in the living room and teabags are being stored in the bath so don't even go there.

There is only permission for triangular tents in the western end of the garden every third Tuesday but only if it coincides with a full moon.

Bababear987 · 12/02/2025 20:23

OP theres no nice way to say this but either you struggle with counting or sense.

Quite often due to snoring or whatever couples sleep apart, the spare room in your plan is free with 0 people in it but you want to keep it free, rather than allow someone to use it? In what world does that make sense, you are the unreasonable one and you sound like hard work, I'm surprised they even want to spend time with you.

HopeItHelps · 12/02/2025 20:23

I thin your sibling IBU to go on holiday with you!

SofaSpuds · 12/02/2025 20:24

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.

I feel like screaming!!! Why, why, why do you keep saying their dp is left without a bed/ share with your DC????? Your sister is taking the spare room, why can't her DP stay in their original room?

Worldwide2 · 12/02/2025 20:25

Wtf?!
You and dp in 1 room
Your sis dp stays in his original room
Your sis stays in box room

Jesus how hard is it?!

Why is her dp having to share with 1 of your kids?????? He can stay in his original room he was sharing with your sis.

Aaaaaaarrrrrggghhhh!!!!!!!

Redfred00 · 12/02/2025 20:25

My child would NEVER be sharing a room with an unrelated adult male. I don't give a fuck about anyone's sleeping preferences. However, a spare room is either SPARE or ALLOCATED. It can't be both.

FcukTheDay · 12/02/2025 20:25

Headache. Where is the troll sleeping?

LilacLilias · 12/02/2025 20:25

It doesn't make sense OP. Why does the sibling and DP's originally planned bed magically disappear if sibling sleeps in the box room which was going to be empty?

Eg -

Original plan
Room 1 - you and your dp
Room 2 - DC
Room 3 - sibling & dp
Room 4 - no one

New plan
Room 1 - you and your dp
Room 2 - DC
Room 3 - dp (alone)
Room 4 - sibling (alone)

Is the issue because you're splitting costs 50/50?

I wonder what conversations are like irl?

I do so feel for the late joiners.

Squirrelblanket · 12/02/2025 20:28

This is the most bonkers thread I've read on here in a long time. Thanks OP, you sound absolutely batshit. 🤣

I read this as "unneutered adult male".
In that case a quick trip to the vet would solve everything.
Unfortunately in reality it appears that OP has already had surgery of their own - a lobotomy.

Cancel the cheque!!

"The plan was that DH and I would have one room, DCs in another, and my sibling and their DP in the third."

OP, you need to explain why your sibling's DP cannot sleep in the third room as originally planned.

Apparently the bed in there disappeared. The second child of OP's also vanished so that there is now space for BIL next to the 6 year old in the second room

RobinEllacotStrike · 12/02/2025 20:28

Has anyone figured this out yet 🤪🤣🤪

Unicorntearsofgin · 12/02/2025 20:29

Are you on glue?

Doggymummar · 12/02/2025 20:29

Jesus Christ OP do the maths

LittleBigHead · 12/02/2025 20:29

RadStag · 12/02/2025 19:56

Still doesn't explain why the child and BIL have to share...

Because @jd206 is assuming that

Room 1: OP and DH
Room 2: Sister and DP
Room 3: 1st DC
Box room: 2nd DC

So of her sister uses the Box Room, the DC whom the OP was going to “accidentally “ put in the Box Room will have to transfer to Room 2

Omg!! This is exactly what I was thinking when I read the OP… I can’t see what the problem is!!

OP we are all confused

Room 1 - you and DH
Room 2 - your DC
Room 3 - your sibling (with or without their DH)
Room 4 - spare room

No one can understand why the sibling DH is sharing with your DC.

RobinEllacotStrike · 12/02/2025 20:28

If course. It's simple. There's a portal to another dimension, that only allows beds to pass through,when, and only when a sibling enters a room with another bed. And then as a direct result a small child and an unrelated man are compelled to share a bed.

It's fairly simple stuff.

FruitPolos · 12/02/2025 20:30

I've read OP's posts three times and I'm still confused.

Bedroom 1 (double?): OP and her DP
Bedroom 2 (double?): OP's sister and sister's DP
Bedroom 3 (twin??) OP's kid (is there more than one child?)
Bedroom 4 (single box): The just in case room.

Why can't sister's DP go into the box room. Please explain, preferably with a diagram.

BigDeepBreaths · 12/02/2025 20:30

I am desperate to hear your siblings side of this. I hope he/she is on MN.

VerityUnreasonble · 12/02/2025 20:31

Just need to think outside the box (room).

The problem is OP has too many children and not enough rooms. Children stay with MIL. OP / DP / DSis / BiL go and stay (OP / DP room 1, DSis spare room, BiL in the bath) room 2 and room 3 become spare.

If children remain with MiL could gain some spare rooms at home too!
