I main think to the code to work also for your homepage is adding the the random function into page controller or homepage controller.

public function RandomChildren($max = 3)
{
return DataObject::get("TouristPlace","ParentID = $this->ID","RAND()",null,"0,$max");
}

should work this way.
It because when you have the function inside the TouristplaceHolder.php it is accessible only from that pagetype and pages extending it..
But if you'll add it inside Homepage.php it will accessible also from that pagetype and pages extending it.

And as most pages extend your page.php and page_contoller.. if you add it inside page_controller .. any page that extends page will have access to that function and you would be able to use it site wide.

hope it solved the problem. . take care..
