I worried about that too when I was looking at the cars XD But I was always leaning towards a sports car as what I would get when the Breeze finally kicked the bucket...regardless of the cosplay obsession.

My father and I have come up with a perfect plan though. NO suitcases. Lay everything in the trunk and backseat and carry a garbage bag. When I get to the hotel, toss everything in the garbage bag to get it up to the room. XD Obviously props will have to be able to fold into tiny pieces and passangers will be nearly impossible to transport on con weekends XD No more car pooling for me, damn.
