Discussion Business Declines on Mykonos and Santorini: What's Really Happening?

I came across some news about a significant decline in business on Mykonos and Santorini, two of Greece's most iconic tourist destinations. Reports suggest that these islands were exceptions in the accommodation and catering business during the first half of the year. There's also talk about 'over-tourism' issues and how this season might be the 'worst ever' for Santorini, according to a local tour guide. Having worked in the tourism industry, I'm skeptical about how these statistics are gathered, especially for places like Mykonos where revenue streams seem almost like a mystery. What do you think is behind this decline? Is it a temporary setback or a sign of changing travel trends?
