$bookings = new Booking;

#foreach($bookings as $booking)
<tr>
<td>{{$booking['id']}}</td>
<td>{{$booking->room->room_name}}</td>
<td>{{$booking['checkin_dtime']}}</td>

<td>
Booking Model
public function room()
{
return $this->belongsTo(Room::class, 'room_id');
}
public function user(){
return $this->belongsTo(User::class);
}

Answer 1

this is your controller code as per the question:
$bookings = new Booking;
$bookings->checkin_dtime = $request->input('checkin_dtime');
$bookings->checkout_dtime = $request->input('checkout_dtime');
$bookings->user_id = auth()->user()->id;
$bookings->save();
you are not adding any room_id column. that means your room_id is null at database. so when you are trying to call relationship, eloquent is unable to build the relationship and you are getting the error. your code should be:
$bookings = new Booking;
$bookings->checkin_dtime = $request->input('checkin_dtime');
$bookings->checkout_dtime = $request->input('checkout_dtime');
$bookings->room_id = $request->input('room_id');
$bookings->user_id = auth()->user()->id;
$bookings->save();
