Royal etiquette

[Pebbles16]

I realise there's probably a specific place for this, but Chat is usually friendly.
My Great Aunt was an internee in WW2 - Pacific. She has been invited to a commemorative event and been advised that she will meet the King. I am taking her as a guest/carer.
This is a VERY BIG DEAL for her. She is totally stressing that she won't be able (physically) to curtsey properly.
With her permission, I am posting here to gauge what is acceptable. I think a bob and nod would be more than acceptable for a 96 year old woman. I have also offered to do the full sweep of curtseying on her behalf.
Any thoughts? I have tried to look at Facebook groups for veterans, but she is very clear that she isn't a veteran or POW.

She doesn't have to curtsy.

Not just as an acknowledgement of her age or mobility, but you don't have to curtsy either. It is in no way expected by the Royals and they have publicly said that.

Congratulations to her and I wish you both a wonderful day.

For someone who's 96 and lived through what she did, no one is expecting anything physical. A warm smile and nod is absolutely appropriate. The King will understand. Her presence alone is powerful.

I’m sure whatever she is able to do will be enough.. I hope you both have a wonderful time.

Wow- am sure she has some stories to tell. At 96, quite frankly, the royals should be bowing to her! Enjoy the day

I've met several royals for a few reasons, all work/award related. We got briefed before hand the first time, told curtsey not necessary and it's Ma'am like ham not Ma'am like arm , please tell her not to worry. FWIW Anne was my favourite, surprisingly knowledgeable in the area we were there for and not frightened to ask very direct questions! Refreshingly forthright.

My 95 yr old grandfather was on the King's birthday honours list and went to Windsor Castle for the ceremony earlier this year. My grandfather is unsteady on his feet and used a mobility scooter to go up and receive his medal.

I wasn't there, but my grandfather said that he apologised profusely to the king that he was unable to stand and bow, but it didn't matter to Charles in the slightest and he shook my grandfather's hand and they had a nice little chat.

Here it is from the official Royal website:
Greeting The King and Queen | The Royal Family

Curtseying is not required, but if you wish to do so, a simple bob is all that's needed. A deep sweeping curtsey isn't necessary.

I hope your Great Aunt has a wonderful day.

Thank you all, especially @HonoriaBulstrode which I have shown to my aunt and she's feeling much better. She would like me to do a proper curtsey on her behalf, but I will not be channeling my inner ballet dancer!
