Do I need to rent a car in West Palm Beach?

Usually not, and often you're better off without one. Downtown is walkable in patches and not between them: Clematis Street, Rosemary Square and Northwood Village are three separate evenings rather than one, and the island is a bridge away. Parking downtown on a show night at the Kravis is its own event. A car and driver makes the three into one night and the bridge into nothing.

Between President Donald J. Trump International Airport (PBI) and neighborhoods like Clematis Street, Rosemary Square, Northwood Village, Flagler Drive, a private captain on call covers everything a rental would, minus the counter, the parking, and the return. You ride, someone else drives.
