I think there's definitely some potential here. Various specialty cocktails (alcoholic and non-alcoholic) scattered around the park that reference old attractions could be a lot of fun. You could almost do a scavenger hunt sort of thing with them (which is why I think non-alcoholic variants would be important).
The naming possibilities alone are endless!
"The Master of Suspense"
"Spooktacular Sangria"
"The Big One"
"Gordon's Last Tour"
"Biff's Revenge"
And so on.
