//remove add to cart from loop if vacation mode is active
function IsVacation(){

$vendor_id = get_the_author_meta('ID'); 
$vacation_mode 	= get_user_meta( $vendor_id, '_wcv_vacation_mode', true ); 
if ($vacation_mode)

	remove_action( 'woocommerce_after_shop_loop_item', 'woocommerce_template_loop_add_to_cart' );

add_action('woocommerce_before_shop_loop_item','IsVacation');

My suggestion…

add_filter( 'woocommerce_is_purchasable', 'woocommerce_rummel_is_purchasable', 10, 2 );
function woocommerce_rummel_is_purchasable( $is_purchasable, $product ) {

    $vendor_id = $product->post->post_author;
    $vacation_mode = get_user_meta( $vendor_id, '_wcv_vacation_mode', true );

    if( $vacation_mode ) $is_purchasable = false;

    return $is_purchasable;
}
