Despite changes which had many fans vocal about the 16th annual Emerald City Comic Con, I found they were not too distracting to the overall experience. Attending the event for all four days than my usual two had me quickly accustomed to the modifications. Walking between hotels was not a big deal. The disabled were able to get around too. Escalators and elevators (twelve of the latter were available) and the slowdown was not completely terrible. Proper planning can allow most to arrive at their respective panel in time.
The added security is a must when considering the climate these days. With more conventions are taking precautions to protect the attendees, they are needed. My pro tip includes having a pouch to keep all items that can set off detectors and staff can see what you have instead of waving a wand.
