The most recent reopening announcement is for AKL Jambo House, and the date is Aug 26, and even then there's no mentioning of Port Orleans. So one can expect Port Orleans and the other All Stars to open much later than that.
Disney is reopening the deluxe hotels first before the moderate/values, probably because they require a lot more staffing so it's harder to do, especially now with all the labor shortages. However, I expect all hotels will reopen by Thanksgiving to cash in on the holiday season. It would be so weird of Disney to miss out on the holiday bucks. And then there's October 1st, the 50th celebration. You would think all hotels should be reopened for that.
