Hard Rock International Chairman Jim Allen told CNBC on Wednesday he does not see a quick return to robust business after its coronavirus-closed casinos, hotels and restaurants reopen.

"There's going to be a real challenge, especially here in the United States, as far as ramping the business back up. We're planning on that taking a year," said Allen, CEO of the Seminole Tribe of Florida's gaming company, which bought the Hard Rock brand in 2007.
