merubah tampilan array bootstrap

selamat sore, saya mohon bantuannya untuk master.. udah saya otak - atik tp selalu ga pas.. saya maunya kalo dilihat pulau derawan (ada 2) jadi di sampingnya, bukan di bawahnya supaya col-md-4 bootstrap oh iya.. kalo boleh di ganti perulangannya dengan while saja hehe. . . terima kasih

 <div class="container">

  <?php
    include 'koneksi.php';

    $sql = "select * from tb_paketwisata";
    $wadah = array ();

      $rows = mysqli_query($conn, $sql);
      foreach ($rows as $row) {
        if (array_key_exists($row['nama'], $wadah)) {
          $wadah [$row['nama']][]=$row['gambar'];
        }else{
          $wadah[$row['nama']]=array($row['gambar']);

        }
      }
    foreach($wadah as $nama=>$paket){
    $x=0;

    foreach($paket as $p){ ?>

    <br>
    <h3><?php echo ($x==0)?$nama:"";
    echo ($x==0)?"<hr></h3>":""; ?>


   <a href="single_event.php?id_paket=<?php echo $row['id_paket']?>" >
    <img src="admin/images/<?php echo $p; ?>" alt="Open Trip Images"  style="height: 250px; width: 300px; display: inline-block; " class="img-rounded">
    </a>


  <?php
    ++$x;
    }
    echo " ";
  }

  ?>
  </div>
