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 Tainer traveled with his father Noonien Soong to Mavala IV.
According to the database, in 2328, Zayra Cabot, Jack Litchfel, David Stipes and Lorine Mendell who all traveled from Gamma Trianguli VI to Tarsus IV requested low gravity suite accommodations. David S. Grant, James Holt, Scooter T. Rocketboy and Richard Sarstedt who all traveled from Tycho IV Spaceport to the Vega colony also requested low grav accommodations.
