SightHoundLover...
One thing I'd like to mention about leaving a bird for so many days is that it might be easier on you, and the bird, is if you prepare him for boarding. Here is a way that I advise my adopters... Take your bird in and board him overnight. Then wait a week and do it again, but this time leave him two days. For an extended period, like the one you are planning, I would recommend another stay for a few days (maybe three) and that should do it. I know it can be an additional expense for you, but I know that this does work well for many owners and their birds.
Another thing is to bring something that is familiar to your bird, like a toy that he likes. Unless, of course, you are boarding him with his cage.
I know that Michael thinks I baby my birds, and maybe I do, but I just think that by preparing them in this way it helps them for the future. Then, if you need to board them in an emergency for some reason, they will already understand the routine. It is just another thing that you can do to help you bird become accustomed to things outside his small comfort level.
Oh, and Michael, of course this was a great article. You always do such a great job. But in this case it was awesome because you mentioned me.
