Vacation need it to relief stress

Ok, I'll explain briefly. We are expecting our fourth joy. My husband it's the only one who works. But right now he is having to much stress at work. That much that he is getting sick and you can see how worry it's him. He told me days ago that he will take a week off wich I consider a good a idea.but I'm thinking that might be better is he disconnect a bit. So trying to find inexpensive two days family vacation ideas. Inexpensive bc money it's not something that we have. But I feel that if he doesn't take a break he would be worst. Thanks in advance for your ideas.
