Just a suggestion, I think we could compare the hotel business with Wonderla’s resort ones.
Like how their resort is built for people who would like to stay for a long vacation and enjoy. Similar goes for the exhibition business here.
Exhibition business I believe attracts international crowd and a hotel very near to the exhibition hall could be really efficient for them.
We can also assume that people who travel here means business and getting a location as close as to the exhibition is huge benefit and they would be ready to settle in a four/three star hotel just for one or two nights. Unless there is a hotel just opposite which provides significant discount.
