For recap: 

It's Kosso's mission. The plan is to scam an arrogant, (currently) powerful hanar (Luek), by faking as guests or servants to his investor/funding party for rich peeps on a yacht, during a giant storm on the hanar's home planet.

Going off memory here, but Jenna and Roland were supposed to be general support. Get some guns/weapons, watch out for the crew, get ready to help the ones in trouble, etc. Volt wrote how Jeanna was stuck with some old unpleasant fellow and Roland completely missed the hint that she wanted to get rid of said fellow. 

Roland tried to wander the ship outside of the acceptable party room (since there's nothing much else at said party room), got caught by a guard, made the excuse he was going to the bathroom, and got thrown into the security room.

Tanya and Kosso are trying to eventually convince Luek to show them around, to get to the place where all his stuff is.
Marianna was finishing talking to her mother, last I read. Got some info out of it too, I think.
Tzvi and Kygg are infiltrating and all that as servants, going to the security room with faked permission (right now).
Kas and Steveo were distractions - Steveo freaked out the door guard and dressed in unique fashion to get attention (also made himself a Spectre). Kas starting talking tech, which caused a crowd arguing about tech near the bar.

Mark was a bodyguard of one of the -genuine- guests at the party, got fired, then got crowded at the bar by guests and caused a fight with one of the bodyguard (Quantum) bosses. He's in the security room with Roland.
