You can always attend as an observer, just watch and not participate in debates, I doubt that 1/2 of a fractured province would carry too much weight.Well, if you do, make sure you stock up on cure disease potions. Northern Elsewyr is currently pro-Empire, south declared independence and is embargoed by Valenwood (you can do some espionage here). For Valenwood, I assume the south-western area, cities of Woodhearth and Greenheart would still be under your control (or contested). Also, 300 ships is a gigantic loss. That's the equivalent of the US Navy loosing their entire fleet. I would cut down that number a bit seeing some ships would have escaped or scuttled.

300 ships is the equivalent of pearl harbor.
