Tegan: It's beautiful.
The Doctor: For some, the Eye of Orion is the most tranquil place in the universe.
Janus, lovely Janus, playpen of the gods! Verdant, balmy, warm and sunny, this luxurious planetoid, habitable solely thanks to Hephaestan grav-field technology, is the home of the Universal Government and every plutocrat, Vidflix star and criminal mastermind of any note and hardly anybody else.
Mercurytaville, a paradise planet unlike any other. Every being on this world has achieved maximum harmony... and maximum hedonism.
