Hate the waking up early rubbish
Pure nonsense.
You do you and let everyone else do them.
And yes, 8 or 9am is not a lie in. And no, not all young children have to get up early. I've looked after countless including my own and I still got to lie in. If one was dropped off at I then I'd go back to bed with them or doze on the sofa whilst they played depending on their age. Babies and kids can be trained either way so all these parents getting up early are just martyring themselves.
On holiday I hate breakfast ending at 10am, so we get up at 9.40 get there just before they pack up, load up our plates then eat at our leisure.
Nothing worse than having to get up before I'm ready. Which some days can be 10 or 10.30am.
So you carry on enjoying your holidays your way but I don't understand why you are even thinking about how others spend their holidays. I don't think there is anything wrong with getting up early so why do you think the reverse? Why is it even a matter for judgement?
I get up most days at 10am, is your mind blown? Sometimes even at 11am.
