Over at the Polynesian, it has been reported internally that that resort had its refrigerators replacement completed in July, but letters went out last week for people with September arrivals. All recent reports from August report working refrigerators.
Obviously each resort is different, but I wouldn't say that a letter = no refrigerator.
I have read reports of people who didn't have refrigerators at POP not getting a refrigerator credit.
So, a bit of wait and see I guess.
