(Walk away Denz. I'm sure that along will be a distraction as they take a moment to make sure you're leaving. Let Iffa make another attempt. If that doesn't get it, Andro can walk up and cold-cock a guard; we'd all take on the nearest guard, get a couple good hits in and rush the ship. Only other thing I can see to do is we all back off adn try another approach, but I'm doubting that is very feasible at this point. As Ush said, we're being forced into action here.
If we do end up in a fight, maybe we shoudl forego the use of sabers even defensively until we're on the ship at least. If the gurds on the ship figure out they're dealing with a team of Jedi, they may figure they're screwed no matter what and just kill the senators as a parting shot. If we look like random rabble, they might figure the outside guards can take care of things, at least for long enough for Jedi to get onboard and take over.)
