Bad Bunny’s concert residency is set to bring fans from around the world to Puerto Rico this summer, and travelers can expect to pay up to see the singer perform in his home country.

The Grammy Award-winning artist’s “No Me Quiero Ir de Aquí” (I Don’t Want to Leave Here) residency will take place at the Coliseo de Puerto from July 11 to Sept. 14, ushering in a “peak period for tourism,” according to Discover Puerto Rico. During this time, an anticipated 600,000 concert goers will descend on the island to see the popular singer.

Depending on the specific concert dates, travel costs to Puerto Rico this summer will come with a premium, according to travel platform Hopper, with round-trip airfare costing 42% more than it did at the same time last year.

However, there are still some good deals to be discovered if travelers plan strategically. “If you’re planning a trip to San Juan, we recommend looking at traveling for the first two weeks or final two weeks of the residency,” said Hayley Berg, lead economist at Hopper.
