If your tour includes a compartment with shared bathroom facilities, it is possible to upgrade your compartment to include private bathroom facilities.
The compartments with private facilities are located on the upper decks of the carriages. They are slightly bigger than the ones on the lower deck (4,2 m²) and have their own shower and toilet. They also come with a small table, a mirror and a bath towel.
Please note that compartments with connecting doors are only available on the lower deck. There is no child discount available.
