Help with conditional statement for custom taxonomy

Hi,
On a custom post page template I need to list the custom taxonomies associated with that post. Some of the custom posts have different taxonomy terms and some have none. So if they don’t have a taxonomy term associated with it then I don’t want the title to show. The following code is omitting all the information, even if there are terms associated with a taxonomy:

<?php  if(taxonomy_exists('','attractions','')) { ?>
<div>
<h2>Attractions</h2>
<?php echo get_the_term_list( $post->ID, 'attractions', ' ', ' | ', '' ); ?>
</div>
<?php } ?>

Could someone please help?
Thank you!
