You do, the and there's a full door to it so the access isn't bad. For one person it's a brilliant tent for the money. It pitches all in one, seems pretty stable even in moderate winds (I haven't had a really windy night in it yet), and all the bits seem well made. At 2.1kg it's not as light as many, but light enough not to worry too much considering how much other stuff I carry normally on tour.
The poles are external, and colour coded and there's no fraying of the sleeves yet. As they are outside of the flysheet though, I agree they should be pretty easy to fix if needed.
The advantage I would see in having a second zipped door on the other side is if you have two people in the tent. As the doors are on the side, anyone on the non-door side would have to clamber over the other occupant to get in and out.
As I understand it the 3 person version of the tent has a door on either side.
