Yes, in 2026, a reservation is essentially mandatory if you want to secure a sunbed or a dining table at any Nikki Beach location, particularly in hotspots like Dubai, Saint-Tropez, or Miami. While the beach clubs occasionally allow walk-ins for "bar-only" access if they are under capacity, the global popularity of the brand means that sunbeds and cabanas are often booked weeks in advance for weekends and holidays. Most locations require a minimum of 2 to 24 hours' notice for digital bookings. Furthermore, many Nikki Beach venues enforce a "minimum spend" requirement for reserved beds, which varies by the day of the week and the proximity to the pool. Entering without a booking often results in being turned away at the gate by security, especially during "White Parties" or signature brunch events. Always check the specific 2026 dress code for your location, as "Beach Chic" is strictly enforced alongside the reservation policy.
