Trump Plaza

Trump Plaza is a fancy hotel in New York City.

History
Once, the queen along with her son Charles and daughter-in-law Diana were visiting the city and decided to stay at the hotel. However, a Skrull disguised as Invisible Woman stole her crown as part of a plan to discredit the real Invisible Woman and Fantastic Four.

Background
It is unknown which building Trump Plaza is supposed to be. The entrance looks like a fancy hotel. Trump did own the Plaza Hotel but lost much control by the time the series was in production, and it was never called Trump Plaza. The various buildings across the world, including New York City, called Trump Plaza are residences and would not be used by the Queen on a trip.
