With the Olympics in Paris this summer, Europe is going to be crowded.
One particularly challenged destination is Greece. This is because 30,000 visitors a day to the Acropolis, coupled with a massive heat wave, have contributed to a health emergency.
And then, there are the cruise ships, where passenger arrivals jumped 50% last year.
Authorities are trying to limit Acropolis visitors to just 20,000 a day, and the Greek Prime Minister is now suggesting limiting the number of ships at ports like Santorini and Mykonos.
Translation: if you can, wait to go to Greece until September.
