Am I being the arsehole here?

[BertieBottsEveryFlavourBeans]

Am I being an arsehole for not wanting relatives to stay in our flat, camping on an airbed for 3 alternative weeks during the Summer holidays?

There is a lot of backstory to this but the crux of the issue is this relative expects to come and stay with us, sleep in our living room (we don't have a spare room) and is upset when I have said it's too much for us and suggested an Airbnb, booking a shorter visit and maybe staying with us a few days instead.

Relative moved abroad but comes back for several weeks during the Summer and over Christmas.

I like my own space and want to spend the time I've booked off over the Summer with my kids doing what we want to do, without having to host someone and change my plans to accommodate them.

So based on the above, am I an arsehole for feeling like this?!

Not a chance would I say yes. I no longer even allow people to stay for one night.

I couldn’t put up with that. 2 nights max if I was in a very good mood (drunk) when asked.
Not fair on your dc either.

You do not have a spare room. It's not practical to have them camped on the living room floor.

The answer is a flat NO, N O.

Thanks for the input everyone.

To add a bit more context, it's my mum, she is a lot to handle and very full on. I struggle with her in long doses because she is the only person who can press my buttons the wrong way without even trying. When she is hear I have to change my plans to suit her (last time she was here she kicked off because I didn't want to go for a coffee with her after dropping my DD off at ballet, because I use that time to go to the gym and she thought I should change my plans)

She has now messaged my DSis saying that she will never see the grandkids again because I don't want her around. I suggested maybe making it a 2 week visit, booking an Airbnb for a week and then splitting the other week between me and DSis, which APPARENTLY was me saying she is not welcome at all and will never see her grandkids.

She lives a 7 hour flight away so I understand she wants to stay for a longer time, but her being here disrupts our routine a lot, and with sleeping in our living room DH doesn't feel like he can chill out like he usually would and has said before that it's too long for her to stay with us. And now I'm the bad guy and she is ignoring me 😐

So it would be week at ours, week at DSis x 3 each, 6 week visit in total.

I feel bad but we have time booked off to spend with the kids and I want to spend it with them doing what I want to do, not what might suit someone else.

It also makes it awkward for other people to visit, her and my dad are long divorced and it wasn't pretty, so he can't drop in when she is here. It's also awkward for DH to pop in and visit with her being here.
