Mobile technology has altered the way the world does just about everything. With mobile devices in our hands (smart phones and tablets) and media and information up in The Cloud, the possibilities for immediate, worldwide, personal access are limitless. Smart mobile devices are dictating how we live our lives and as a result, these developments are game-changers for all businesses, but especially for service industries, including the hotel sector. These advancements are literally redefining how guests interact with a hotel in virtually every aspect of its operation, and savvy hoteliers who are implementing the latest mobile technologies and best practices in each critical channel will steal market share from their competitors, decrease dependency on their Online Travel Agents, and generate incremental revenues which will substantially increase their bottom line. A well-defined mobile strategy is no longer a "nice-to-have" but an essential weapon in an industry that is evolving at a blistering pace, and those operations that are slow to respond do so at their peril. The January Hotel Business Review will examine which mobile strategies some operators have adopted in order to meet these challenges, and will report on the solutions that are proving to be most advantageous for both companies and their guests.
