The name Astoria Carlton-Ritz is a pun on two famous hotels - Waldorf-Astoria and Ritz-Carlton.
When one of Astoria's board members tells her not to cry, she responds with "It's my party, and I'll cry if I want to." She is quoting a line from the 1963 number one hit by Leslie Gore, "It's My Party".
The skyscraper the party takes place in is identical to the Avengers Tower
