Marriott International CEO Arne Sorenson said Friday the hotel chain experienced "lots of cancellations" after the deadly March 22 terrorist attacks at the main airport in Brussels and a city metro station.
"Sadly, we've been through this a little bit before," Sorenson told "Squawk Box" on CNBC. "This will be a few weeks [or] maybe a couple of months, and then folks will start to come back again." That's provided no new attacks are carried out in Europe, he added.
Following the deadly November Paris terrorist attacks, bookings at Marriott hotels dropped 20 to 25 percent, Sorenson said.
