Don't be disheartened. We just booked a trip one month ago to take a big holiday overseas in December. I have never even played around on the reservations website before and was really shocked to learn people do this 180 days in advance!
I literally just got Ohana's about half an hour ago for 5 on 12/12 at 7pm! I've checked once or twice a day and missed numerous days over the last month but today I have checked about 4 times throughout the day. I got Ohanas and California Grill at 5:35.
The only 2 I'm now desperately after is CRT and Chef Mickey's. Again today CRT came up for 3 people (my girls and I) for a 2:00pm lunch on the 12/16 but I stupidly hit back to fill in my login details. Went back in, was still there but when I went to proceed it was taken
I was so close!!! 
Just keep checking. I've rang up a few times as well but they've never found anything different for me, so now I will just stalk the site!
