I definitely would rule out Rancho. You would need to walk on the road rod a couple of miles…too dangerous. We stayed numerous times at Mt Vernon and walked most days to Club O area. We are not young,but in good health and enjoy walking. It would take about 15-20 minutes to reach exit casino. That is a lovely walk,especially before 9 a.m. when the beach is still pretty empty. Enjoy!
