This was my first NDK since 2002 and I have to say what a difference 9 years makes! I had fun and have some minor complaints:
Pros:
~ The Hot Seat with Leah Clark and Todd Haberkorn (And Chris!) was the funnest, BEST panel I have ever been to at any con ever. It was fun just hanging out and talking without worrying about virgin ears. More of those please!
~ Generally, all the panels I went to were really great and I went to a lot of panels. The panels were above my expectations, I didn't even find as many to go to at Anime Expo than I did here at NDK. Battle Karaoke was a blast because I was on the winning team

~ The con goers at NDK were really, really nice. I met a lot of great people who were friendly, but not in that weird creepy way, and a pleasure to talk to. I had been out of the anime loop for awhile and con goers were so helpful and answering any and all questions I had about anime and other things without making me feel like a noob. Special shout out to mystery girl in one of the Autograph lines who had a list of everything the voice actors at NDK had done ever so I didn't miss anything

~ Speaking of Voice Actors, what a great list of guests. I'm usually not one to fangirl over voice actors but they all won me over by being so sweet and charming and SO NICE to the con goers. I saw Michael hanging out in the hallway just talking to con goers and being super sweet, which was great to see. There were also so many, which was great.
Cons:
~ Holy hell was it crowded. I know AX has more space, but it was way more closed in than AX. I wasn't expecting that but eventually got used to it.
~ The lines were so long, like unbelievably long. I waited for Vic's autograph for 2 hours, A group Autograph for an hour and a half (And didn't get in

), the Costume Contest for a hour and a half, and the Hot Seat for 2 hours. This was pretty typical for any panel/event/autograph session and, while I was expecting it for the autograph's I wasn't for the panels/events. At AX panels lines were short and you could walk right in, so it took some time getting used to. A LOT of my con time was spent in a line though, probably 75% of it, which was sad, I really wanted to spend more time taking pictures of the cosplayers.
~ The Staff was rude. I heard them barking at people who didn't really deserve it and yelling at people who stopped for 5 seconds to say hello to someone, or just say they liked a costume. Like, constantly. I kind of wanted to yell back we aren't sharks and don't need to keep on moving all the time. Most of the time they weren't even blocking anything or upstrucking traffic. As for me, While we were waiting for the Cosplay Contest, when we sat up to go into the room I realized I had to pee, like really bad. So I thought I could get in, get my seat and then go to the bathroom. I asked a staff member who told me if I left I would lose my spot in the room and not be able to get back in. So I spent 2 hours in a chair with a full bladder about to pee in the seat. It was pretty extreme.
This isn't to say all the staff was rude, I really wish I would have kept a list of all the nice staff members and gave the list to ops at the end, because there were more rude ones than nicer ones it would have helped narrow it down. The Vic Autograph staffers were so, so sweet and trying so hard to keep people from passing out up there

. There were also some panel/event line coordinators who didn't yell at the con goers and were so polite, but I didn't get their names

.
~ I have one suggestion. I have Severe Panic Disorder which is brought about my three things (Usually): Lots of people, a tight space, and heat. Not one of three things, all those three things usually have to happen and boy did they ever for the Autograph sessions. The tiny, cramped hallways full of people so when you looked ahead of you, you saw no exit, only more hallway and people. The heat coming off of those bodies in a windowless area making the air thin and warm. My disorder is 95% controllable with Medication (Before anyone says "Why come to a con then!?") but those lines were deadly. Just the autograph session lines, mind you, but if you ever want to feel like a trapped animal, that is where to do it. If you could find a better spot for autographs... that would be lovely.
Speaking of, because of this, I have to sometimes leave a line and walk around for a awhile, so I don't agree with no saving spacing or else I would be completely screwed. At AX it was One person can save for One other person which worked out pretty well for me, since I could get out of line without getting into trouble. This is also true if I see the line is in cramped corners, I let my friends go and I go walk around, it's just more convenient than having EMTs follow me around.
~ Oh One more suggestion! Bring Japanese music acts to NDK! They don't have to be big acts, but NDK is definitely becoming big enough to warrant such acts.
But yeah, we had a lot of fun. This was my boyfriends first NDK and he already wants us to prereg for next year.
