Going to Hawaii in September with our 2 7 year olds. First San Francisco for a few days then Hawaii. Planning on visiting HNL but what other island is great for kids? Not sure about a car in HNL but for sure in the other island. Need to stay at a Wyndham hotel as we have points to use. The beach is great but not the most important thing at the island. We live close to the beach and its hot all here. If we like it we will go back next year to a different island. Planning about 11 days in Hawaii.
