The Hilton New Orleans/St. Charles Avenue is available for $5/night prepaid, non-cancellable from July 12 through July 17 or dates inside that period. (It may be available other dates as well, but I haven’t found other periods where the rate is offered, and no other dates have been mentioned in this Flyertalk thread as yet.)

All room types including suites appear available at this price.

If you book at Hotels.com you can earn a $75 prepaid Mastercard for the booking under this current promo for 4 night or longer stays.

As always, you might consider waiting to book airfare to see whether the deal is honored (although sometimes booking airfare can help if you’re negotiating with the hotel to get them to honor the rate). My preference is not to book until they’ve had time to determine how they are going to handle things.
