Answer:
focused differentiation or niche marketing
Step-by-step explanation:
When a company focuses on the needs of a small but very specific groups of people, they are carrying out a focused differentiation strategy on a niche market. Niche markets are usually very small, but they are made up of consumers who really know what they want and are very specific about what satisfies their needs. E.g. vegan restaurants serve niche markets.
In this case, Golden Group hotels is focusing on the 1%, or very wealthy customers that demand special amenities and are willing to pay a very high price for them.
