Otakon AA Question!

Anyone out there purchased empty AA tables at Otakon before?  Interested
to hear experiences, when/what time you got to set up, how many spaces
were open, that sort of thing.  I haven’t been back to Ota since my
first time a few years ago (lottery system woo) but I will have my new
book out when it rolls around THIS year, so I’m wondering if it might be
 worth it to schlep out to Balti and take my chances at snagging a
no-show.
