Abstract Forecasting hotel arrivals and occupancy is an important component in hotel revenue management systems. In this paper we propose time series approach for the arrivals and occupancy forecasting problem. In this approach we simulate the hotel reservations process forward in time. A key step for the faithful emulation of the reservations process is the accurate estimation of its parameters. We propose an approach for the estimation of these parameters from the historical data. We considered
