Hi! I'm a solo traveler and will be visiting Seaford and the Seven Sisters Country Park this August. I would very much like to also go for a swim on the beach in Seaford but am concerned about what to do with my belongings while I do so. As I will be traveling alone, there is no one with whom I could leave my bag (a small ladies' purse with my valuables). Are there lockers available nearby perhaps? Or some other type of way to keep it secure?
