AIBU to use main bathroom on holiday despite en suite?

i don’t think you’re in the wrong for using the nearest toilet for a quick wee.

I’m just wondering whether you’ve commandeered the en suite for your own sole use.

Is your DH allowed to use the en suite?

It's often just about privacy. I'm sure she won't defecate on their toiletries, although visitors might like the look of something and give it a spray or squeeze out a dollop to try; but even the thought of somebody potentially looking through your personal stuff is unnerving.

And who says it's only shower gel, shampoo and the like? What if they've left Canesten, Viagra, condoms or other 'personal' items in what they understood was their own private bathroom?

You are on holiday in a property with one bedroom and one bathroom per couple. The lounge and kitchen are for use of both couples presumably and then each bedrooms and bathroom are private spaces.
Surely you can see that OP. You aren’t the only person needing bathroom privacy.

The spooky corridor story is nonsense, - you are a grown up.

I wouldn’t dream of using their bathroom.
It’s very bad manners to assume the right to do that. Especially rude to continue to do it after having been given the heads up that they don’t appreciate it.

if you were staying in adjacent hotel rooms, would you assume the right to wander into their bathroom ?

That's even worse. They seem to have a problem with you specifically.

This backs up my opinion then. DS and BIL have been having a moan about you getting the en suite because of your needs so they are making a point about it by stopping you using the main bathroom.

I think they have a bee in their bonnet about you requesting the en suite room (even though I completely understand why) and they are just trying to make a point about it. Maybe they feel that you made a big deal about the en suite (not sure if you did or not) so they are just getting the point across in a very clumsy way.

We had similar last holiday i went woth my sibling, there were 2 loos one was an ensuite and they had that room. Their child likes to spend ages on the loo and was insisting on using the main loo which is fine they are a kid but my daughter nipped to the ensuite to pee (she was 6 at the time) while her cousin was in the loo taking a 25 minute pee and my sibling shouted at her for using their ensuite. It was said at time of booking that the kids might need to use the ensuite if their dc was doing his marathon toilet sessions and agreed this was fine. This and a few other behaviours have put me off holidaying with them again tbh and if the corridor freaks you out why are you going back ?

Yes YABU. We go away with DH'S family twice a year. Usually a big rental house, different bathrooms on each floor, not everyone gets an en suite every time. It's a given that whoever doesn't have an ensuite takes one of the family bathrooms and no one else uses that. It's only fair if you have your own that they have their own too.

And hee husband who says she does the same at home.

The issue here isn’t the bathrooms as such, it’s that OP needs to be able to access a bathroom quickly at night, and also keep one bathroom for stinky stuff so that other people don’t have to put up with that.
The question is unanswered as to whether the en-suite is available for everyone to use at their own risk or whether it is restricted for the OP’s sole use.
As others have said, two couples, two bathrooms each couple uses their own. OP YABU

A dark, spooky corridor? Are you a child?

I bet your sister’s dreading the entitlement already. I can’t believe you kept using it for 3 days. You ‘insist’ on the en-suite, you ‘insist’ on using the main bathroom, your sister must be a saint.

Then don't have the ensuite this time. Let your sister and BIL have the ensuite room. I take it your IBS means you sometimes need to go NOW, well if someone was in the main bathroom, you would be justified in using the other toilet.

Sounds like you are being selfish and I would be peeved too ... What's yours is mine and what's mine is my own. Had I been granted the security of the ensuite I would certainly listen to any requests for me to limit myself to it. It's about respect. They are respecting your privacy and all they ask is you respect their request. Gently, I would also think about how you behave at home as your DH seems to have an issue there too.

plus they've probably put all their toiletries in there.
What do you think the OP is going to do to their toiletries? Use them? Steal them? Shit on them?
I think they're being weird and territorial for no good reason. Of course it's fine to use the nearest/least spooky loo for a quick wee. Having your own en suite doesn't mean you're disallowed from using another loo.

Yeah, I think its a bit odd to use the main one if you’ve got your own, and particularly if you asked to have the en-suite.
We live in a big-ish house. I walk past 3 bathrooms to get to our en-suite, which I do every single time!

We go away with family and friends a lot. Everyone sticks to their assigned bathrooms ensuite or main. If there is communal loo, then all use that or their own as they choose. On that basis YABU.

Two bathrooms. Two families.
One each.

Pick the convenience of the ensuite you need to also use the spooky corridor. How old are you BTW?

You can insist on everyone bowing to your needs and then doing what you want on top of it. As for the corridor, grow up.

Well then this year are you going to give them the bedroom with the en suite, and you exclusively use the main bathroom?

would that suit you?

It doesn't really matter what mumsnet thinks. The fact is it bothers the people you are with. Do you really want an argument every time you go to the toilet? The fact that they said it to you multiple times and you continued to do it is crazy to me. You know you're annoying people.

That's a point I hadn't actually thought about: if OP starts declaring that she 'only needs a wee' before swanning in to the 'main' bathroom, that kind of leads to a 'culture' whereby everybody may feel the expectation to announce and justify what they're going to do before using that bathroom - even though DSis and BIL don't actually have anywhere else to poo (or wee, for that matter).
