The watersports place next to Pearl Beach is the bargain on St Jean, at €10/chair and €15/umbrella. Further down the beach, Lil'Rock has reduced their prices to €20 for June. The €50 was probably farther down the beach at the Eden Rock hotel, where along with your expensive chair, you're sometimes serenaded by the sound of hydraulic rock drills as they continue with their post-Irma rebuild/expansion.
