Best for travelers who want direct Atlantic beach access, a large on-site spa, and multiple signature restaurants (including Nobu).

Best for guests seeking a marina-centered Boca Raton base with Hilton Curio branding and easy access to Mizner Park and local docks.
When Eau Resort & Spa wins: choose Eau if you prioritize an Atlantic‑facing private beach, a very large full-service spa (42,000 sq ft), a wider roster of on-site dining (Nobu, Angle, Breeze, Stir, Savor, Oceana), and dedicated family and adult spaces (kids’ clubs plus an adults-only tranquility pool).
When Waterstone wins: choose Waterstone if you want a Boca Raton location close to Mizner Park and South Beach Park, prefer marina and Intracoastal views over open ocean, and value a smaller, Hilton Curio–branded waterfront resort with on-site boating and conference facilities.
Bottom line: both properties are polished waterfront escapes but serve different coastal preferences—Eau is the choice for ocean/beach and spa-focused stays, Waterstone is an alternative for a marina-centered, Boca Raton experience.
