I sympathise. I am still trying to decide whether to stay in a private room in hospital this August, because *at night* the public wards give me all the problems you mentioned - noise, fear of people suddenly walking in for totally innocent purposes, wondering whether I or someone else is going to fall out of bed / trip over something on the way to the loo, the nasty mattresses - but during the day, the isolation of a private room might kill me.

Ho hum.
