There is more happening in the world that is affecting the fate of hotels in particular cities.
Increased attacks, changing traveller behaviour and large-scale medical risks are impacting the demand for hotel rooms and, subsequently, the rate. These cannot always be foreseen although can sometimes be factored into forecasting, as shown in a recent PwC report.
Istanbul and Rio de Janeiro are some of the major cities affected by matters they can't control, as explained by Pauline Houston, global director, hotel community at American Express in this video.
Business can also affect a hotel's fortune. Pauline shares her thoughts on the repercussions of the fall in travel by the energy, resource, marine and mining industries.
This interview is part of a series that Business Travel iQ conducted at this year's Business Travel Show.
