They are all different. In the retirement village near me some own their bungalows and are living independently (except for the emergency button) the residence have to be 55 to purchase. Then other residents live in the main house and need much more care so maybe the people in the main house have to pay for living quarters.
If the visitor quarters are serviced then I would imagine there would be a charge for using the room. Much like a hotel, it has to be cleaned, supplied with soap and toilet roll, and the bed linen changed afterwards.
As far as I'm aware, ummmm is right- they all have different set-ups and different rules. You would need to speak to that particular place to find out what their policies are.
"Visitors' quarters" are usually separate from the actual apartment and are booked and paid for separately. Is he staying in her actual apartment, or in a separate room?
the mother has said she has to pay like over £20 per night for the son to stay in a separate room - she is only in a one bedroomed apartment but she is willing for the lad to sleep on the settee per se.
yes, if the son want to be in a separate room, there is a charge. In my Mother in laws place there was a room that visitors could use (well it was more like a mini flat) that you paid to stay in
