To never invite them again.

DS and his girlfriend went to a paid for attraction of their choosing. Girlfriend complained the entire way round that certain small sections weren't open

Did your son tell you this ? Surely he would have had a go at her too ?

So he needs to be angry and upset at the right people, which isn’t you.

Like I said, your dad and your son are behaving quite similarly. Lashing out at the wrong people. Only your dad is a lot older and wiser.

So if I were you I’d tell your dad to keep you out of it and tell your son to ring him and your mum and apologise.

(I’m leaving the GF out of it as she’s not someone you can do anything about.)

This. Why on earth didn't you nip it in the bud from the outset? I would have offered to pay her ticket home as soon as she opened her gob. Ticket home or smile and shut the fuck up would be the early options. Anything slightly off colour after that would be met with a trip to the airport or local train station for her or both, whatever.

Just keeping schtum has enabled her over inflated ego to give full rein.

Utter rubbish.

This.
She should be invited over very soon to apologise to your parents for a start and then not encouraged to come again until she learns some manners and accepts that the world does not revolve around her.
Can you imagine having her as a DIL 😱.
As for your son, he should apologise to his grandparents too.

Don't even think about inviting them again. Tell DS why not. Take your parents somewhere nice to make up for it.

Obviously you won’t invite them again and I doubt they would accept if you did.

You said DS is golden child for GPs and the GF has been lovely when staying at yours a few times a week, so it sounds like thi sis massively out of character for both of them - in which case, maybe give it a bit of time and then try and talk to DS about it again with the intention of finding out if anything else is or was going on?

I don't mean that what they did was okay even if there is something unusual going on. Calling them out on their treatment of your DPs was the right thing to do. And not inviting them again is a reasonable response to how they behaved. But if they were both out of character, it is a hint that something unusual may have been going on for them and, as I assume you love your DS (despite the holiday!), you might want to see if he needs some support.

People are on holiday and might want to be up a bit later than 11pm. There is a happy medium that most good hotels strike between a place acting like a guest house in Bognor Regis in 1978 and a club 18/30 🤪

Another tale to cement my view that holidays with extended family are utterly atrocious.

I would never entertain anything other than going with just DH and DS.

Why wouldn’t the hotel bar close at 11pm like everywhere else unless it is a club 18/30 hotel? Most places don’t want to encourage all night drinking.

YANBU, though I am always slightly incredulous myself at hotel bars closing at 11pm.

You did a nice thing. It didn’t work out. Your poor son is saddled with a misery, astonishingly ungrateful of both of them. Buy a card and gift for your parents and move on. Your ds won’t be invited again.

RTFT.

And it's spoken, not spoke.

I’d actually suggest you go away with your parents next time and DS isn’t invited either!

The fact they came and didn’t even offer to pay is so rude. Make it clear she will not be coming on any future holidays and that you need a break from seeing her. And that until your son apologises
profusely to the grandparents who paid for his trip that you won’t be helping him with anything. I’d ask my son to move out honestly. Give him a real kick up the backside!!

You never know how children are raised unless you actually you see them around their parents.
You say her parents never holiday with her - however, it could be they never took her (or any of her siblings) on their holidays. Ever.
Maybe her parents were quite standoffish during her lifetime, employing babysitters while they went on holiday after holiday and out with their friends and spent weekends away in the countryside.
I know a family exactly like this and the mother and daughter didn’t connect until the daughter got cancer - and then it was too late. I watched with sadness as they spent the last few months together when they could’ve had a lifetime.
Your son is probably embarrassed. Given time I hope he comes to realise that his grandparents are precious and he owes them much more than an apology.
I’m very sorry about your vacay and your parents. They didn’t deserve any of that.

In real life I think parents are very cautious about banning a partner from their house as they don’t want to lose their child. I think their behaviour is atrocious but everyone’s said their piece, id probably take some space now. Although if they stayed together it would be really really hard to not say things like ‘would you like to come for dinner? Is gf coming? Do you think she can manage not to criticise every single part of the meal i cook?’

id try and go on a weekend away with your parents. Son not invited this round. Gf never ever invited.

I agree with above - he's getting his shag and that is his number one priority, so he's unlikely to break up with her any time soon.

I wouldn't let her in my house again.
Good on you for bollocking them both.

Shocking behaviour on their part! I'd not be having her in my house ever again. At least now you know why her parents stopped taking her with them on holiday in her teens.

Maybe that's just the way she is , but your son still likes her so give her a break?

I’d suggest they send a thank you card to your parents for the holiday & apologise in there.

How old is your DS and GF?
