Thank you to Duane Zimmerman for contributing this old image. The Omni Hotel was part of the Omni International Mall that was built on the north and east sides of the long-standing popular Jordan Marsh store. The hotel and mall opened in 1976 and featured Jordan Marsh as the south end anchor department store and a J. C. Penney's as the north end anchor department store. There were two levels of other national chain stores, a movie theatre, and restaurants in between the anchors. The Omni mall also had a "Treasure Island" - a children's entertainment area with a Florida-themed carousel, video games and other rides and carnival type games. Jordan Marsh closed in the early 1990's, Penney's closed afterward and the mall was in a downhill spiral, finally closing in 2000. Two floors of the Jordan Marsh are now an art school.

The hotel has changed brands several times and is now the Hilton Miami Downtown with 527 newly renovated guest rooms including 58 suites that overlook Biscayne Bay and downtown Miami.
