Any recomendations for staying on the water for three days? We would like to stay somewhere between Discovery Bay, Stockton and Bethel Island. We have a 27' boat, a slip is not necessary but would be nice. A vacation rental in Dicovery Bay at $400+ a night is too pricey for us. I've noticed Windmill Cove, Viera's and B & W. Any advice would be great!
