I'd cancel. Two years ago, my husband and I were in Spain on a beach we know well. He went into the water and suddenly I couldn't see him. I knew he hadn't drowned as he doesn't go out of his depth. The beach was a mile long. I was burned by the sun as I ran up and down looking for him. Finally I asked the life guard to help. she had a walkie-talkie and talked to another life guard at the other end on the beach. He was found after 30 min sitting on someone's bed on their towel as happy as Larry! I've not been on holiday with him since.......Too stressful.
