Facts and Figures about the Five Biggest Hotel Groups Worldwide

In March, we had a deeper look into the facts about the five biggest hotel groups of the world. According to a study of the MKG-Group in June 2010, the five biggest hotel groups worldwide are the British IHG with 643,787 rooms, followed by 3 US hotel groups, the Wyndham Hotel Group (597,674 rooms), Hilton Hotels (587,813 rooms) and Marriott International (580,876 rooms). The French Accor Group is the 5th largest hotel group with 492,675 rooms in 2010.

We compared them analyzing all available hotel reviews from 41 sources like Tripadvisor and Holidaycheck all over the world. We looked at the TrustYou-Score of all hotels (that normalizes grades in different scales e.g. stars, school grades, 1 – 10 points, thumbs up or thumbs down, etc.) and at the number of comments with positive, neutral or negative tendency.
