All psych wards are different and it also depends on the nature of who is in there.
It also depends on if it is public of private.

The only way you can tell what a particular ward is like is by asking some-one who has been in that particular one. They all vary alot. I have been in the same on a few time and my experience changed with the mental stability/instability of other around me.

A private hospital would be better. They have programs that should keep you occupied. If you are being booked into hospital ring and ask if they have run programs. Google the hospital.
