I know how you feel,
here is my personal opinion, when you pay for 5 star, you or the implied expectation is privacy, a more private experience by way of butler/wait staff,
you also dont expect kids screaming and running down the corridors ,
so most of the people paying top dollar would probably expect that level of privacy and quietness
on the other extreme, if you stayed in a hostel or 1 star, everything is rough, rooms are smaller, communal facilities, etc etc, and you are forced into more interaction, youd probably be silly to stay in a 1 star hotel and expect complete privacy unless the hotel is empty
I am quite an extroverted person, but prefer more privacy than having to interact with multiple strangers in things like meals, rooms, pools, massages,
im happy with activites to be with others
