Wow I got back last night and my experiences were the polar opposite of the above poster.
All Star Music CS- was not that busy. I usually stay at POP and I was amazed at how this smaller food court seemed so much less crowded.
Chefs De France- checked in 4:45 for 5:00 ressie- seated in 5 minutes. Server Yvan was excellent.
Kona Cafe- Checked in 6:50 for 6:40 ressie due to over napping

. Waited about 15 minutes. Our service was a little less spectactacular, but it was just our server. I asked another server for a refill and got it immediately. I think our server was just a little forgetful. Not horrible though, just not as good as the night before.
Concourse Steakhouse- Checked in at 5:15 for a 5:30 ressie and seated in what had to be less than 10 minutes. DS wanted a penny from the penny machine by the elevator so we got that while waiting and then DH wanted a drink from the Outer Rim. As he got up to the bar to order the buzzer went off.
Service again was excellent. My Filet ordered Medium rare came out Mooing, but it was quickly fixed and all was well.
Boma- Breakfast ressie 9:45 AM. We woke up to check out, clock said 8:00. I sprang out of bed, woke up family, got all showered dressed, finished packingand were ready to get out the door. DH picks up his watch off the table and says "what time is our ressie?" I say "9:45" he says "We have two hours!" Called Disney dining who said there were no earlier ADR's available.
DS 4 had been messing with the clock the night before and must have set the clock ahead 2 hours. Which means we went to bed at like 8:30 the night before! I knew it didn't feel like 10PM!
Anyway we took a breather, meandered down to the car and packed it, drove around to the front of the resort where I had them remove my one day base tickets from my KTTK for future use. We then drove over to AKL and arrived at Boma at 9. Told the CM we were early. She said "No problem!" We were seated in less than 5 minutes.
Service was excellent, as was the food. We didn't care for Boma for dinner, but loved it for breakfast.
