"There are four main two deck Holodecks on deck 9/10. These have separate rooms for monitoring and controlling the simulation."

There are 20 other Holodecks but these are only one deck high. These are located on decks 12 and 22.

There is a Marine and Senior Officers only holodeck in the Marine section of Deck 8.

Hoodecks are used not only for recreation but also for Crew training and also my Wedding."
