When going the main road to Dizin there is a hotel about five minutes before you reach the slopes. It is slighly cheaper than Hotel Dizin. More importantly it will probably have some rooms in peak season (most notably weekends). It has a free bus to the slopes.
This hotel was built by, like the lifts and the slopes, Zie Germans in the good times of the shah in the seventies even has a bar. Now it is a cafe with a cool retro feel to it. The staff at this hotel.
