Fusion Maia Resort, Hoi An, Vietnam

Indulgence levels are off the scale at beachfront boutique hotel Fusion Maia Resort. Set within tropical gardens, Fusion Maia’s day spa is the largest in Central Vietnam; irresistibly, all spa services are included in the room rate, from manicures and massages to all-out pampering sessions, including a seven-day holistic program. To keep you feeling relaxed, the hotel has an infinity pool that seems to flow straight into the South China Sea, as well as a little library and a gym.
