Companion Care Needed - Care.com : Job Details

I need senior care provider with experience with memory loss/dementia. Primarily looking for companionship throughout the day as the two geriatrics would wander if left alone. Assistance with toileting (basically walking to the bathroom and reminder to wash hands). This would be for 2 seniors. Our family is staying at a hotel for the weekend and would need assistance for one day while we attend a local event. Would need care giver to stay back with the grandparents to make sure they are safe and assist with obtaining meals. Thanks!
