What are the most famous hotel consulting management companies in the world and at home?

There are many hotel consulting management companies, which are very detailed in the United States. Some specialize in finance, some do catering, some do mysterious guests, and some do laundry service. If we say that the most famous ones are HVS, PKF and HTL (Haohua), because they have the largest business, among which PKF was merged by CBRE. Jones Lang LaSalle said that there is also a special hotel consulting department upstairs. In fact, the "big four" (not the big four) all have their own hotel departments, because they are engaged in property management after all. To do commercial real estate, hotel brand matching is necessary, and Jones Lang LaSalle is the best. What is better done in China is gorgeous. There are many other hotel consulting companies, but the scale is still a little far from the beauty of being a local strongman in China. The subject said that he wanted to go to an investment resort in Africa, so I suggested that it might be better to find a consulting company with a branch in Africa, because they have first-hand data. HVS, HTL and PFK all have offices in South Africa. It seems that PKF also has business in Zznja. After all, it depends on CBRE. Do you want to do feasibility study and valuation (whether to consider mergers and acquisitions? ), I personally think HVS may be better.
