/**
 * This example shows how to add a hotel listing group tree, which has two levels. The first level
 * is partitioned by the hotel class. The second level is partitioned by the country region.
 *
 * <p>Each level is composed of two types of nodes: `UNIT` and `SUBDIVISION`. `UNIT` nodes serve as
 * leaf nodes in a tree and can have bid amount set. `SUBDIVISION` nodes serve as internal nodes
 * where a subtree will be built. The `SUBDIVISION` node cannot have bid amount set. See
 * https://developers.google.com/google-ads/api/docs/hotel-ads/overview for more information.
 *
 * <p>Note: Only one listing group tree can be added per ad group. Attempting to add another listing
 * group tree to an ad group that already has one will fail.

"""Shows how to add a hotel listing group tree with two levels.

The first level is partitioned by the hotel class. The second level is
partitioned by the country region.

Each level is composed of two types of nodes: UNIT and SUBDIVISION.
UNIT nodes serve as a leaf node in a tree and can have bid amount set.
SUBDIVISION nodes serve as an internal node where a subtree will be built. The
SUBDIVISION node can't have bid amount set.
See https://developers.google.com/google-ads/api/docs/hotel-ads/create-listing-groups
for more information.

Note: Only one listing group tree can be added. Attempting to add another
listing group tree to an ad group that already has one will fail.

=head1 NAME

add_hotel_listing_group_tree

=head1 DESCRIPTION

This example shows how to add a hotel listing group tree, which has two levels.
The first level is partitioned by the hotel class. The second level is partitioned
by the country region.

Each level is composed of two types of nodes: `UNIT` and `SUBDIVISION`.
`UNIT` nodes serve as a leaf node in a tree and can have bid amount set.
`SUBDIVISION` nodes serve as an internal node where a subtree will be built. The
`SUBDIVISION` node can't have bid amount set.
See https://developers.google.com/google-ads/api/docs/hotel-ads/overview for more information.

Note: Only one listing group tree can be added. Attempting to add another listing
group tree to an ad group that already has one will fail.
