First of all they encourage walks. Activity is preferred over being sedentary. I don't know about you but if I had to stay in my PJs the whole time there I would have been very depressed. It was only a couple of days after leaving the hospital that I returned to "normal" life, at least in appearance. And that was more effective in bringing about a PMA than anything else I did.
I was there in March and I spent as much time outside the building as I could. The day I got out of the hospital I was outside on the veranda when Brassard came by. He looked at me and said, "I thought I just performed major surgery on you!" and smiled. You can't keep an old broad down!
We've been there twice and we've never heard of anyone's things being taken. Valuables (money, jewelry, wallet) should be kept at the nurses station though.
