Yes, it was a wonderful experience. My Mom may not look 91, but over the last year, she has developed some very significant health problems and really should not be living on her own or driving any more. I have really noticed how her memory has deteriorated too, which could cause some significant problems with taking medications.
Both my sisters are 24/7 caregivers to their spouses. Two of my nieces took time from their jobs, to take over caregiver duties so that they could attend the retreat. For my sisters, the retreat is a little island of personal peace and sanity, in a world where they really cannot call any time their own.
