That's because you probably hung around Margaritaville instead of by Positano near Sheridan st. Locals know to stay away from the band shell unless you want to mix in with the homeless and rift raft.
Head to Hollywood beach. Park closer to Sheridan than Hollywood. Less people and less rift raft. You can always walk the boardwalk South to Margaritaville to show them the Flo Rider and pool.
