We were there 3 or 4 years ago. Stayed at the Drift Hotel. It's a few blocks from the beach and surprisingly cheap. It was renovated but still had a 1950's retro feel to it. https://thedrifthotel.com/
Great meal at Coconuts. https://www.coconutsfortlauderdale.com/ It was loud and crowded, but atmosphere and food was great.
We took a harbour cruise one evening and saw the homes of the rich-and sometimes famous. I'm not talking athlete rich, but hedge fund rich. We also saw J.K. Rowling's yacht on the cruise. If I remember the name of the company I'll edit this post.
