The pest control island hardly ever has randoms but sometimes does, on the boat no randoms what so ever but you need at least 5 people there to get a game going and you cannot alch in the game so finding a good world todo this on can be hard.
Not sure if this works, but you could go to the lander in PC in a world with hardly anybody in it. That way the pc game never starts? not sure if there are randoms there though, but prob not.
