Once into the city proper, initial scouting must focus on locating a temporary headquarters. HQ should be small, out of the way, defensible, and easily hardened against casual patrols and inspection. You'll need to hide right under their noses.
I suggest the sewers for temporary HQ. If the draconids are not already using them, then it's secretive, and even if they are, a sewer HQ would be easily mobile.
The only issue this brings up is collapsing the tunnel upon escape. Collapsing the sewer could have detrimental effects on the city above. Maybe we want that.
Anyway, I'm finished with my final, so I'll be here all day.
