My husband and I and our two boys ages 5 and 2 will be spending two nights in the area (a Sunday and Monday) and wanted a hotel near a sandy beach. We'd like to visit Mystic and its attractions, but also have access to a beach. Are there any beaches walking distance or a very short drive from a family-friendly hotel? or if it is better to stay in Mystic, what would be an easy beach to get to. Thanks!
