With its historic buildings and 150 canals crisscrossing the city, Venice, Italy, is a dream destination for many. But day guests—tourists who visit for less than 24 hours—are making that dream into a nightmare. According to tourism scholar Magda Antonioli Corigliano, the longer a visitor stays, the smaller their impact on the city. One-day guests try to pack too much in, she says, and overtax the city’s resources and infrastructure as a result.
That’s why the city is introducing an entry fee for day tourists, which will be between 3 and 10 euros—or about $3.15 to $10.55. All visitors must prebook their trip so the local government has a sense of how many visitors there will be each day.
In the U.S., the National Park Service is taking a similar approach for its most popular—and crowded—parks. If you want to climb Cadillac Mountain at Maine’s Acadia National Park or see Old Faithful blow at Yellowstone National Park, you need to plan ahead.
These famous spots now require reservations in advance for peak times to ensure that they aren’t so packed with people that it becomes harmful for the environment. And if you don’t have a reservation? Kupper suggests going elsewhere in the same park! “Spend more time in that one park and see it really, really well,” she says. “This helps the environment as well.”
