A low gravity suite or low grav suite was a type of environment available to travelers as special accommodations on transport ships.
In 2370, Lieutenant Commander Data accessed the commercial transport database and searched the passenger manifests of the ships SS Manoa, SS Kogin and SS Wisconsin to find proof that Juliana O'Donnell traveled with his father Noonien Soong to Mavala IV in 2328.
According to the database, in 2328, Zayra Cabot, Jack Litchfeld, David Stipes, and Lorine Mendell, all of whom traveled from Gamma Trianguli VI to Tarsus IV, requested low gravity suite accommodations. David Grant, James Holt, Scooter T. Rocketboy, and Richard Sarstedt, all of whom traveled from Tycho IV Spaceport to the Vega colony, also requested low grav accommodations.
