Yup. Went over to the shopping center, down to the park, over to the beach, on the beach, and back. We rent bikes for the length of stay and pretty much someone uses them every day.
Yesterday, my brother rode on my dad's bike on the beach...for the first time without training wheels. He scared himself several years ago and gave up learning. Now that he's two inches shorter than my dad, he could use my dad's bike, and since it was on sand, we could get him to ride and he knew that if he fell, it was on sand. He didn't fall though, and managed to master the skill while we were there. We could tell he was very proud of himself too.
