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?

If I've read this right, I wouldn't be happy that my child was sharing a room with your sister's partner.

This 💯

Yep.

OP is a thwarted CF

But this isn't needed. The OP for some reason has created this batshit scenario because for some reason they absoloutley have to leave a room spare.

Not sure why you are getting such a hard time here OP

It's like everyone is acting like people don't normally book holiday accommodation with a room to be kept empty at all times in case someone gets ill?! Weird!! 🤷🏻‍♀️

Who on earth does this 🤣 also if someone did get ill, good lord the DP could just move back into the room with his wife. Not that it's hugely likely!

Madamecholetsbonnet · 12/02/2025 19:31

Does the Spare Room lead to Narnia?

Hankunamatata · 12/02/2025 19:31

BUT WHY WOULD 6YR NEED TO SLEEP WITH ANYONE - THEY WOULD BE WOTH THEIR SIBLING

Purplebunnie · 12/02/2025 19:31

I've read all OPs updates and I still don't understand why if her 6 year old wasn't sleeping in the box room why they are now having to share with their siblings DP. It just doesn't make sense

Hesma · 12/02/2025 19:32

You make absolutely no sense @jd206. you and your dp have one room, dc have one room, sibling has one room and their dp has one room. Simples! You’re being totally OTT… 🦇💩

You mean Spare Oom

SDTGisAnEvilWolefGenius · 12/02/2025 19:32

Why can’t your child share a room with their sibling, as per the original arrangement, @jd206? Your child is being expected to stick with the original arrangement -they are not being expected to change it - unless your stealth plan was for them to use the box room the whole time, so your dc each had their own room.

If the room was intended to be a bolt hole for anyone on the trip, then your son wouldn't have been able to use it every night anyway, so I can’t see what the problem is.

jd206 · 12/02/2025 19:11

It’s not about keeping the room empty for no reason, it’s about the fact that the original plan worked for everyone, and now my sibling is unilaterally changing things to suit themselves, which has a knock-on effect on my DC. The box room was always just a spare—not a main bedroom—so there was a reason for it not being assigned.

If they’d said from the start they didn’t want to share with their DP, we could have worked something out. But deciding last minute that their DP has to bunk with my 6yo instead? That’s not fair. Why should my child’s sleeping arrangements be disrupted just because my sibling doesn’t fancy sharing a bed?

You’re literally nuts.
A bedroom doesn’t need to be left space in case someone gets sick on holiday, plus you clearly just mean incase you or one of your kids get sick since apparently it’s not an option for your sister to sleep in the spare room!

Hopefully your sister just cancels the trip because who could be arsed going away with someone so rigid and inflexible.

PandaTime · 12/02/2025 19:32

Can I just point out that the OP's posts are all annoyingly gender-neutral so we have no idea if the space-hogging sibling is a man, a woman, or a furry, nor whether their partner is a man, woman, or whatever.

pictoosh · 12/02/2025 19:32

Think OP really really wanted the wee box room kept spare. I have no idea why.
There is no problem here. Rooms for everyone.

Floralnomad · 12/02/2025 19:32

@jd206 you need to explain how your sisters partner sleeping in what was an allocated empty room means that he is now sharing with your 6 yo . You are either very very drunk or just being deliberately obtuse , either way YABVVVU.

No, you haven’t read it right. To be fair it’s batshit confusing 😂

OswaldCobblepot · 12/02/2025 19:32

10 pages in and still none the wiser.

PumpkinSpicedLatte · 12/02/2025 19:33

“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’m confused by this part? Who is the DP that’s got to share a room with your children? You said you and your DH have your room, kids have theirs, your siblings partner and themselves have a room and one spare room, so why are the kids suddenly needing to share with an adult? Or am I going mad?

listlovers · 12/02/2025 19:33

Room 1: OP and DH
Room 2: OP’s DCs
Room 3: Sibling
Box room: Sibling’s DP

You’re welcome, @jd206

Strictlymad · 12/02/2025 19:33

I still don’t get it, if sis wants the ‘d and v’ room why can’t dp just stay in the double? And dcs keep original bunk?

IchiNiSanShiGo · 12/02/2025 19:33

BitOutOfPractice · 12/02/2025 19:20

I wish I wasn’t doing dry February. I feel a large glass of Sauvignon Blanc would make this make more sense.

I’ve just poured my second and can confirm - it still doesn’t make sense.

Why does this all mean DSis’s DP has to share with OPs DC, when DSis presumably knows the DC so would be the obvious person to bunk with them? IF THERE WASNT A SPARE ROOM SHE COULD USE WHICH WOULD SOLVE THE PROBLEM?

thepariscrimefiles · 12/02/2025 19:33

Picklewicklepickle · 12/02/2025 19:12

The only way I can make sense of this is that OP is still planning to keep one room spare, meaning:

Room 1 OP and DH
Room 2 DC and Sibling DP
Room 3 Spare
Room 4 Sibling

God knows why they need a spare room on holiday at the expense of others having to share!

But she only mentioned her 6 yo sharing with her sibling's DP. Where is the other child sleeping?

Mumofteenandtween · 12/02/2025 19:33

I have the most amazing and brilliant suggestion! It is so genius it is no wonder that no one else came up with it.

Take a deep breathe everyone and prepare to be amazed…..

Bedroom 1 - Op and her partner
Bedroom 2 - OP’s kids
Bedroom 3 - OP’s sister’s partner
Boxroom - Op’s sister!

I know! It is just amazing!

Now - I don’t mean to be presumptuous but I do believe that the Birthday Honours are coming up soon and it would be a massive but lovely surprise to find myself nominated “For services to room management”. Just a thought….
