Can you drink alcohol on Cumberland Island?

Can you please clarify the rules regarding alcohol consumption on Cumberland Island? I understand that it's a protected area with unique wildlife and natural beauty, so I'm wondering if there are any restrictions in place that limit or prohibit drinking alcohol while visiting the island. Is it permitted to bring your own alcohol or are there designated areas where alcohol consumption is allowed? Additionally, are there any penalties for violating these rules? Thank you for your assistance in clarifying this matter.
