According to the hotel regulations, the second largest 1 premium is reasonable, a little higher than 1.2 meters.

According to the policy of most hotels, for two families with 1, if the child's height exceeds 1.2 meters, it is usually necessary to pay extra bed fees or premiums. This is because in most hotels, the size of standard single bed or double bed is usually only suitable for children under 1.2 meters in height.

However, the specific premium amount and policy may vary from hotel to hotel. Therefore, it is recommended that you carefully read the hotel policy and confirm its requirements before booking a hotel to avoid any unnecessary expenses or disputes.

In addition, if you have any questions or dissatisfaction with the hotel's policies, you can choose to communicate with the hotel and seek solutions.
