edited: I just realized I am answering for Beach Club, not Boardwalk. Sorry - I don't know if it's the same at Boardwalk.
It is Green Clover and Aloe from a company that is/was called
Scentair or ScentatHome. They changed their name and structure a few years ago.
They really sell commercial scent machines, but we bought one a few years ago. Unfortunately, the refills were $40 or so (monthly subscription type thing), so I cancelled it after a year. We still have the machine though, so someday if I feel flush I might sign back up.
Others have said that there is a similar scent at Bath & Body Works, but I don't know what that is called.
