Important Note on Berdyansk Travel:

Due to the ongoing conflict in Ukraine and the current occupation of Berdyansk since February 2022, providing a travel guide based on “real, verifiable data” for tourism, typical costs, current activities, and safety in May is not possible. Travel to Berdyansk is currently unsafe, highly discouraged by international authorities, and subject to severe restrictions and dangers.

As an AI, I am programmed to only use real, verifiable data and never make up statistics, prices, or facts. Given the critical geopolitical situation, information regarding tourism operations, prices, crowd levels, and accessible activities is not verifiable for safe, normal tourist travel. Providing any estimates would be speculative and could inadvertently mislead users about the current reality and safety of visiting the region.

Therefore, I cannot fulfill this request by providing a guide that adheres to the strict “real, verifiable data” and “never make up statistics, prices, or facts” constraints for a travel guide to Berdyansk in May.
