Companion Care Needed

About who needs care: I am looking for someone to provide Respite Timeout relief. My sister is 76 lives with me in North Port. She has the early stages of dementia, but can mostly take care of herself. In addition, she do not believe anything is wrong with her memory. However, Florida judges have disagreed and have granted me plenary guardianship. I am looking to periodically get away for a day or two days. About the care needs: Nothing special. My sister is happy all day to set in front of the TV with remote control with a bag of potato chips and a Pepsi. She doesn't cook. Meals (except for breakfast ) will to be prepared which I will do, which will need to be warmed up for eating.
