My parents (79 and 80, with multiple health and mobility issues) have decided that they want to drive to the beach, about a 10-hour drive under ideal circumstances. Dad says he will do the driving - he hasn't had any accidents yet but has had several near-misses and is very aggressive behind the wheel. Flying won't work because of their health, mobility issues, and size (Mom is very overweight). I have offered to drive them but they have rejected my offer. They have taken a bus tour to the beach once before, but complained constantly about their difficulty getting on and off the bus, not enough bathroom breaks, seats were uncomfortable, etc. Any suggestions?
