Zastros 8
From Tardis Wiki, the free Doctor Who reference
Zastros 8 was a peaceful world, with attractions such as sunshine, seas, seaside resorts and computer sciences.
The Sixth Doctor tried to take Melanie Bush to Zastros 8, but the TARDIS acted up due to the interference of the Nathemus and instead took them to Zastros 9, its counterpart. (AUDIO: The Brink of Death)
