I've done the race a few times (er, 11) , and my main advice when it comes to aid stations is simple:
Always be prepared to skip the next aid station. Always. We have a lot of awesome volunteers and 99% of the time you will get what you need and fast. But every now and then something goes sideways and the proverbial fecal matter hits the air circulation device. One year, one of the two water filters at A-Frame broke. They could not filter the water fast enough to fill the bottles. Those who skipped the Barr Camp station were screwed. (They now pack in 3 filters, but that didn't help folks that year. These are big, heavy filters, not the tiny things you find at REI or Cabelas).
Unlike a race where they can just drive in a replacement on a 15 minute notice, getting to places along the course takes a lot of planning and time. You cannot call an uber to get to A-Frame or Barr Camp.
So, always always always fill up the hand bottle or whatever you have at every chance. For me, this means Barr Camp, but I can punt that to A-Frame if needed. For others looking for a refill at NoName, don't skip the refill option at the Incline aid station.
There are also one thing you can do to to make things go smoother: Never use a narrow mouth bottle. Those are a pain in the ass to fill. I ran the Cirque aid station for 3 years. Folks would spend $200 to enter, $500 for flights, $300 for hotels, and then show up with a water bottle they picked up at walmart for $0.75. It takes a long time to pour water into a 1/4 hole. The wide mouth ones fill wicked fast. I can dump and not worry about 90% of the water hitting your feet.
The second thing is to always be proactive and start to yell what you want as soon as you start to approach the aid station. If you want water, start yelling 'water water water" as you approach. It improves the odds that the gal holding the water pitcher will yell back and you will meet up before it is too late.
As Mark noted below, blowing through an aid station will cost you big time once you get above A-Frame. Plan to spend 30 seconds at each and you will be a lot better off above A-Frame.
