Capturing information about hotels at airports

While travelling, if a layover is more than six hours, travelers generally like to rest. Since the travelers might not be possessing a visa for the country that they are transiting through, most dormitories or hotels are located within the airport. As a logical next step, we can capture information about hotels at airports, so that travelers can use the information to plan their journey better. Considering there are multiple airports in a city, it is imperative to show only those hotels that are located at the airport through which the traveler is transiting.
