Answer 1

To achieve what you want you have to fetch all room categories, loop through them and then loop through the each room category rooms.
This is example code:
public function index()
{
$room_category = RoomCategory::with('Room')->paginate(1);
return View::make('pages.roomlist', compact('room_category'));
}
Your view:
#foreach($room_category as $category)
{{$category->name}}
#foreach($category->Room as $rooms)
{{$rooms->name}}
#endforeach
#endforeach

You don't need get() method if you are using paginate. Replace this
$room_category = RoomCategory::get()
->with('Room')->paginate(1);
with this
$room_category = RoomCategory::with('Room')->paginate(1);
EDIT
It would be good if you don't use pagination links for room in your index page, just paginate your roomcategory.
$room_category = RoomCategory::with([
'Room' => function($query) {
$query->latest()->limit(5);
}
])->paginate(3);
On your index view paginate the categories and make a link to each category page and paginate your room their
index.blade.php
#foreach($room_category as $room_cat)
#foreach($room_cat->Room as $room)
<div class="room-section"></div>
#endforeach
View more of this category
#endforeach
{{ $room_category->links() }}
Your Controller
public function showCategory($id)
{
$room_category = RoomCategory::with([
'Room' => function($query) {
$query->latest()->paginate(8);
}
])->find($id);
return View::make('category.show', compact('$room_category'));
}
and category/show.blade.php you can paginate room
#foreach($room_category->Room as $room)
<div class="room-section"></div>
#endforeach
{{ $room_category->Room()->links() }}
