Our condo is a little further south than Corona del Mar. We have never rented a golf cart, always walk or bike everywhere.
You could probaby walk to Fido's in 10 minutes from Corona del Mar, but you'd be 'power walking'.
You could try moving just a little south and stay at Belizean Reef or the Palms this time. Before we bought here, we stayed at Belizean Reef. Nice condos. Nice location. Owning here, I'm glad to be a bit further from town.
