It took one electricity bill to crush Dimitris Diavatis' hopes that his Greek summer resort could bounce back to its pre-pandemic health this year, even with bookings pouring in.

The amount was more than double what he paid this time last year when the hotel was not even open. After two sluggish summers, the irony was not lost on him: "We won't make a profit in a good year," he said. "It'll be eaten up by inflation."

Greece — like the other tourism-dependent economies on the euro zone's Mediterranean fringe — is seeing signs of a much-needed recovery in visitor numbers in 2022 after two largely lost years. As in Spain, Portugal and Italy, the sector is a huge employer and contributor to state revenues.
