Oh. Well be prepared for a ton of people gawking at you during your demo, there's a very small space and tons and tons of by passers (but i'm sure you already knew that). I think that one does "group" demos, but I think that depends on what time of the year it is, they do a lot of hiring at certain points of the year (usually sept-october, before xmas) and then that one i believe does group demos, but probably not this time of year.
Good luck! That counter's relatively small, so it should be easy to navigate and find everything you'll need.
