[LAU] Looking for voice recording suggestions

Hi there, I'm currently taking part in a game jam and I'll have to do a whole lot of voice recordings tomorrow. I have barely any experience with that. I do have a laptop, USB audio interface, mic, stand and a bunch of questions. 1) Room: Besides corridors and such I have access to a roughly 2x10 m room or a bigger room, I guess 10x20 m. I guess go for the bigger one? They are both rather empty, safe for tables and chairs. 2) Recording software? Ardour, something simpler? 3) Post processing, normalization of some sort. I'll have at least four total amateur voice actors and all in all hundreds of lines. 4) What did I forget? Thank you in advance for any suggestions. Best regards, Philipp
