"Credit" might be a strong word in this case.

Universal is clearly set up -- and staffed up -- like they expected a different event. They seem to have been caught flatfooted just like everyone else. I hope they don't cut staff only to have October return to normal.
Best theories I've heard are (1) Five Nights crowd is younger, has to be home at a decent hour, and (2) guests are priced out of Express and think S&S the only way they'll be able to see the marquee IPs without a 2 hour wait (which, of course, everyone else thinks, defeating the purpose altogether). Bars have been relatively empty as well lately, which I suppose could support either theory.
