Revolutionary novelty in the field of hotel service became "short circuit" of all services of hotel on one specially trained operator. Per 1993 group Westin has presented the program Service Express allowing the visitor to order any service of hotel through uniform service service. Program At Your Service SM from Marriott has been started in 2000 and also allows to solve any problem of the lodger by means of one call. Similar project One Touch Service was realized by company Radisson SAS. As a rule, such service unites economic service, kons'erzz, service of messengers, business center, a dry-cleaner, restaurants, the improving center, the centers of entertainments, engineering service and service of telephone operators.
