Am I being selfish.

Don’t feel guilty. Accept the invitation with good grace, and have a lovely time.

No doubt your D would not want her invited family to sleep in a cold room.
Why not wait and see the arrangements once you arrive and I am your son is quite capable of sorting out any heating arrangements for himself.

Surely, as it's your daughter's house, it's up to her where people sleep - she's assigned you a nice room next to a bathroom, so respect her wishes and enjoy it ! (Also, as we get older, we have to gently give up the habit of putting everyone-else first and put ourselves first for a change. You should definitely have the more comfortable room!)

I always give up my lovely bedroom with adjacent bathroom if I have guests, and sleep on the harder bed in another room myself. I do have access to a nearby bathroom though. I am lucky enough to have 2 . However its usually only for one or two nights. If going to a relatives or friends for the night I am usually given a very comfortable room near the bathroom.
Don't feel guilty as if you say you think your son should have the better room everybody else will feel guilty and say you should have it.
Have a wonderful break! Enjoy your family get together!

No age has privileges! Stay put and ? unless you’re asked to swap - don’t offer!

I'd check that I would deffo be in the 'comfy' room before I booked my flight -

Abuelana I strongly disagree with you. Strange thing to say.

As others have said...I'd check where she plans to put you all!!

I think you all should sleep where your daughter asks you all to.
It's her house and she will decide where's best for everyone. I'm sure she will give you your good room near the bathroom and you'll be comfy.
Enjoy your break. I hope you have a lovely time xx

I hope you've made sure you ARE getting the nice cosy room...

My answer to you, don’t be daft, what do you want to do that for?? Surely as an elder in the family you deserve a bit of comfort.

Hear hear Pat1949

Abuelana I think I read you wrongly. Please accept apologies.

No of course don't swap - being a senior member of the family must count somewhere! If it's cold, I'd guess that your GD will be providing extra bedding etc and anyway, they may well be some of the last ones to bed anyway !

No dong give up your room x but you are so lucky I’d sleep standing up to spend Christmas with my daughter and grandchildren but the flight are too dear - hope you all have a lovely time x

I'm assuming you 'know' you'll be put in the more comfortable room? If you are (and I certainly hope that is the case) at an appropriate time I would make verbal reference to the relief I was experiencing and the reason for that. This would reinforce the importance in everyones' mind. Certainly wouldn't do any harm and would bode well for your comfort zone in the future. Good luck.

No need to feel guilty. Its one of the few benefits of becoming older!
I'm always given the eldest GSs bedroom when I stay in Oz, usually for 6 weeks at a time. He doesn't really like sleeping on his own so takes the top bunk with youngest GD (7) or goes in with the 2nd GS (12). I feel sort of guilty, but he's quite happy. My DD despairs - he's 15. She couldn't find him recently, and there he was downstairs in his sister's room! Maybe he'll go straight from home to living with a wife....?

As the others have said, enjoy the comfortable room!
We end up in the spare room at our DS' house, sleeping on an inflatable bed in our sleeping bags - but we camp/glamp quite happily, so I suppose they think we're OK. And we are - except for trying to get up from virtually floor level!! Last time I noticed that they'd tidied the room so we had more space and they have been talking about a folding double bed, so I'm hoping......

agree with mumofmadboys. tis not your choice to make. its your daughter's house. she puts you in the nice room. there is no issue here.

This falls into the category of giving up your own room to a guest - no! My parents always did this when their good friends came to visit and I could never understand it! As others have said you're the senior member of the family and will be much better for you to sleep well!
