I am told sunny is almost guaranteed till noon. But that paths get muddy and unpleasant to walk during this time. And that on occasion there are several days of full on days in row. I don't envision spending money on a car rental but there are tuk tuks for when it's not raining 🤷🏻‍♀️ Don't know how the system works but when I was on Lake Atitlan, Guatemala I could just go out and pretty soon could wave a Tuk Tuk to take me where I needed to. I'd be 8 min walk from the beach which is a great plus. And the beach would be cool to walk. I am gonna sleep on it.
