What to do in West Palm Beach for someone who has never been? Meeting my boyfriends mom for the first time who lives there

Long story short, Im (27BF)I’m realizing that what the mom(60WF)wants to do doesn’t really align with what I enjoy. I’m more of a relaxed, curious type. I love going for walks, exploring historic sites, and discovering really good food. I’m artistic, fun, and open-minded, but she seems to have a lot of high-energy ideas that feel a bit overwhelming. My boyfriend (35WM) is helping finding suggestions but nothing sticks. Since it’s my first time visiting and I’ll be arriving this weekend, I’m struggling to think of something we could all do together that wouldn’t feel forced. Any suggestions?
