Yes, for the few interiors that I have to do, I need something (I usually use Dynalites, but really any strobe/pack set with extension cables will do). It's a two-day shoot, and usually when I fly somewhere to shoot something like this, I've been able to rent lighting, stands, big tripod, even sandbags. I think I can survive with three strobes, and perhaps the Novatron kit would even suffice (though admittedly it's not the most 'robust' system). I would bring my camera stuff, plus a couple of portable flashes, gels, and even an extra umbrella or two. Don't know that I could fit a strobe kit in my bags though!
Even thought about driving out, but it's about 1300 miles one way, so it's not in their budget. Flying plus lighting rental is though.
