Using content from different pages

I currently have /cruises/index.php with this code:

<?php
                    perch_content_custom('Content', array(
                        'page'=>'/cruises/*',
                         'template'=>'holiday_listing.html',
                         'sort'=>'title',
                         'sort-order'=>'ASC',
                    ));
                    ?>

But the 'problem' I have is that I have content on /cruises/another-folder which I do not want to show on /cruises/index.php

Is there a way to only show one level rather than all sub folders too?
