A holosuite uses transporter technology to create holographic images in much the same way that a holodeck does. However, holosuites are in wider use than holodecks and are not limited to starships. There is also more variation in holosuite design than holodecks.
The Ferengi entrepreneur Plegg is credited with designing the first holosuite and is responsible for its subsequent spread across the galaxy. (DS9: "Body Parts")
Some wealthy individuals have their own private holosuites, although due to the costs and maintenance this is uncommon. (DS9: "Meridian")
On one occasion, more than twenty individuals were part of a baseball simulation in Quark's holosuites. It is unclear whether they were all in one suite, or whether the suites were networked, allowing a smaller number of individuals to occupy each suite. (DS9: "Take Me Out to the Holosuite")
