Get_the_terms restrict output

you can change you code a bit :

$taxonomy = 'country';
$terms=get_the_terms($post->ID,$taxonomy);
if($terms) {
    echo '<h1>Holiday ';
    $total_count = count($terms);
    $country_count = 1;
    foreach( $terms as $termcountry ) {
        if ($country_count = 1){
            echo 'in '.$termcountry->name;
        }else{
            if ($total_count = 2){
                echo ' And '.$termcountry->name;
            }else{
                echo ', '.$termcountry->name;
            }
        }
        $country_count = $country_count + 1 ;
    }
    echo '</h1>';
}

This will output in case of one term:

<h1>Holiday in Spain</h1>

in case of two terms:

<h1>Holiday in Spain And Japan</h1>

and in case of more then two terms:

<h1>Holiday in Spain, Japan, England</h1>

hope this helps
