[It's forest that the teams have to pass through to get to the gate. Mentally correct any instances spud's missed fixing from 'ruins'. ;) Unless they zoom across the lake and then stick within the 20-50m distance to the ruins fencing, because there'd be no forests in that range. The genjutsu in that area probably makes you think you're in a minefield or something instead.
The exchange with the Chunin went something like this: ]
Chunin starts to open mouth to answer with amusement visible on his face and gets hit by another Chunin. "What was that for?!"
"She'll get you if you answer a question about that yet, you know."
"Please, like she'll find out."
"You
know what her career is. She'll find out and then you'll be
fucked and cleaning toilets in the public restrooms near the villages gates for the next year while newly graduated genin laugh at you as they go by doing D-rank and C-rank missions."
Higure seemingly appears from nowhere and steps up behind them. "Almost certainly! However, she likes me more than either of you and thus won't have to file paperwork regarding your untimely demise for disobeying her." He checks to see if any other genin teams are present before shaking his head 'no' at the Iwa team. "Have fun, and try not to die! ... until after you've signed liability waivers, at least."
As the Iwa team is leaving, Higure sets down a box on the table one of the two Chunin had just finished setting up. "And hey! I brought some breakfast for you guys setting up this end of things. Feel free to snack on them, and beat up any genin trying to sneak a bite. We can always relocate them elsewhere and claim the injuries were caused by themselves while under genjutsu on their way to the Exam."

At the western gate, several Chunin have taken up some of the chairs under the gazebo and have started waving forward complete teams to hand over exam tickets and sign liability waivers. Other Chunin sit down in chairs around the general area, forming a bit of a perimeter and keeping an eye on the overall area. A table behind the Chunin at the gazebo has several boxes of dango and other pastry that the Chunin snack from as they carry out their duties.
Near the gate to the ruins is the jounin, a woman shorter than just about everyone present. She just watches over the genin while munching on dango. She directs a stare towards the Chunin asked the question by the Iwa team, drawing her thumb across her neck when he happens to glance in her direction before answering.
The Chunin turns back to the Iwa team slightly paler than he had been. "Sorry, I can't answer that until much closer to start time."
Among the teams present so far are 3 Uzu teams, 5 Konoha teams, 2 Kiri teams, 4 Suna teams, 1 Kumo team, and 3 Taki teams. Genin are directed to the opposite side of the gate from the gazebo after they've checked in and signed the waivers.
[note: by opposite side, I mean still on the outside of the fence. If you decide that meant inside the fence, there's a Jounin there ready to chastise you out of the Exams and into the hospital. ;) Because, hey, you already signed the liability waivers at that point!
Also, the reason for the different table/chair amounts is now explained! The chairs aren't for the midgets wanting a sweet jacket, they're for the poor, suffering Chunin helping out with the Exam.
Hopefully this post has cleared up any confusion. And yes, you have to have a complete team to compete. If any of your team is trapped in a genjutsu in the woods or somehow becomes unable to compete, you better get them loose/healed in time or you're out of luck. :D ]
