Where do you expect them to show up?
If you want them to show up in the search results, then you have to either active this option “Show a “More info” link in the store listings?” on the settings page, or use this filter to add them wherever you want.
If you choose to use the filter then replacing the code on line 27-29 with this to show the hours. Do make sure to flush the WPSL transient cache after you make a change with filters. You can do this on the WPSL settings page in the ‘Tools’ section.
$listing_template .= "\t\t\t" . '<% if ( hours ) { %>' . "\r\n";
$listing_template .= "\t\t\t" . '<p><%= hours %></p>' . "\r\n";
$listing_template .= "\t\t\t" . '<% } %>' . "\r\n";
If you want to show them in the info windoow, then have a look at this thread.
