Hall North offers 4,600 m² of usable space and has a retractable telescopic grandstand with 3,000 tiered seats, so that every congress participant has a perfect view of the stage podium. Alternatively, standard ground-level seating is also possible. The integrated and height-adjustable stage measures 10 x 5 meters and can also be used by large vehicles.

Up to 5,000 people can be seated when the space is fully utilized. Hall North can be divided into three segments to adapt the event space. Hall North is shaded as standard.

Hall South has 3,000 m² of usable space and can accommodate up to 3,200 congress participants when seated. It can be divided into four segments for congresses with smaller groups of participants. Floor-to-ceiling windows at the front provide the entire hall with daylight. Shading is possible. Three of the four sub-segments can be completely darkened by separating off the daylight segment.

Congresses can be held in the light-flooded Terrassensaal with an area of 2,400 m² for up to 2,200 participants. If it is instead a format with several smaller groups of participants, the hall can be divided into five individual halls for up to 500 people each thanks to flexible and soundproof partition walls.

With large windows in all room variants, the entire area offers plenty of light and the feel-good atmosphere required for a congress. All window fronts can be shaded if required. The Terrace Hall has its own foyer area, which can be used as a registration area for congress participants, among other things.

In addition to a large plenary session, many congresses require additional space for accompanying smaller presentations, workshops or press conferences. The RMCC is characterized in particular by its room concept. Over 40 group rooms complement the large halls and rooms.

Forums of various sizes offer space for up to 300 people in the RMCC. There are numerous studios on two upper floors, which can be flexibly combined with one another using partition walls. All group rooms are characterized by floor-to-ceiling window fronts and plenty of natural light. Shading is possible. The boxes, which offer a direct view of the north hall, are a particular highlight.

Connected to the Terrassensaal is the 500 m² roof terrace, which is ideal for relaxing congress breaks as well as lunch or dinner buffets during the event.

From the roof terrace, congress participants can enjoy a beautiful view of one of Wiesbaden's many green spaces and the Wiesbaden Museum opposite.

Hall North and Hall South are centrally connected by the light-flooded 1,350 m² foyer . Registration and checkroom areas will be set up here for congresses. Congress participants can access the adjoiningparking garage with 800 parking spaces via the Central Foyer.

Congresses in the South Hall can be held completely undisturbed and independent of the rest of the building in terms of infrastructure. The South Hall has its own light-flooded foyer areas (approx. 500 m²) as well as entrances and access points.

The Terrace Hall also has its own foyer area, which can be used as a registration area for congress participants, among other things, and can be extended by opening the partition walls of the Studio Terrace.
