Yes, guests staying at the Wynn Las Vegas generally have access to the pools at Encore, and vice versa, as they are part of the same sister resort complex. However, access is subject to capacity and specific "Resort Fee" terms. While the main resort pools are shared, some areas like the Encore Beach Club (a "dayclub" with live DJs) require a separate cover charge or a cabana reservation for all guests. If you are staying in the Wynn Tower Suites, you may have exclusive access to a quieter, private pool area that is not available to standard resort guests. In 2026, you should always bring your room key or use the Wynn app on your phone, as pool attendants scan for "Registered Guest" status at the entrance to manage the high demand during the hot Las Vegas summer months.
