It won’t be open for another month, but the Ocean Resort Casino in Atlantic City already has booked its first guest. In gaming terms, it has hooked a whale.

The William Hill company, the most prolific sportsbook in Vegas, will oversee the Ocean Resort’s sports gambling operations. The Ocean Resort is the former Revel Casino, at the north end of the AC boardwalk.

Business is contingent, of course, on the New Jersey legislature’s approval of sports betting, which could come within the next week or so.

The floodgates to that process were opened when the U.S. Supreme Court overturned a nationwide ban on sports betting outside of Nevada on May 14. The Ocean Resort will open June 28.

The plan is for a 7,500-square-foot sportsbook at Ocean Resort that will be in the “heart of the casino’s gaming floor,” according to a release from William Hill.
