I don’t think anyone apart from the Yorks wants the responsibility of Royal Lodge - it’s huge and needs a lot of money spent on it.
I’ve no idea why articles keep popping up
claiming it’s being saved for someone else.
It seems very clear to me that William and Kate definitely don’t want it - out of all the choices they had when they decided to move closer to the Queen and the kids’ school they chose a smaller family-style home not a stately home type of property.
They know within a couple of decades or less they will be living in Windsor Castle and Sandringham etc
Camilla has loads of places to be if she outlives Charles - including her own property. I’m sure William would let her keep living in the Balmoral estate house they use right now. There, Clarence House and her own house which is near Highgrove seem to be the places she spends most time now.
