1. Scale: Wanda Vista is a hotel type under the Wanda Hotels and Resorts brand. It is a brand trademark registered by Dalian Wanda Group Co., Ltd. in 2013. Mandarin Oriental Hotel Group is an international hotel investment and management group that owns top luxury hotels and resorts in well-known tourist destinations around the world.

2. Service: The services provided by Wanda Vista Hotel may be more inclined to meet the needs of the Chinese market, including waiters who are familiar with Chinese guests and room equipment with Chinese signs. The Mandarin Oriental Hotel focuses more on providing global services, including multi-lingual service capabilities and broader global tourism resources.

3. Brand positioning: Wanda Vista Hotel may focus more on luxury and comfort to meet the needs of wealthy Chinese consumers. The Mandarin Oriental Hotel focuses more on providing the experience of top luxury hotels and resorts, including unique architectural design, high-quality services and first-class facilities.

In summary, although both are luxury hotel brands, there are obvious differences in service objects, service standards and brand positioning.
