I have run into many storms in my trips south. Never while headed or returning from Disney, but trust me I've driven in blizzards on the Jersey Turnpike so bad that I had to stop and clean off my headlights because the snow had managed to cover them down to about a 2 inch circle of light beaming through. One hasn't lived until you get stuck behind a grouping of cement trucks with plows, staggered across 6 lane of highway with the far left lane pushing snow into the next lane, being pushed into the next lane by the next lane and so on until the final one is pushing everything off as far as they can to the right. Many of those storms caused me to be delayed but never completely ended.
The Virginia deal was surely an inconvenience but can hardly be called a disaster. Those that think that it should have been a snap to clear up the whole mess have never experienced an actual "snowstorm". They've probably experienced one of those awe inducing Hallmark Card big, light snowflake type heart warming snowfalls. Nature doesn't care who you are or where you are going. It can be mean as hell. To my knowledge no one died or was injured and it just simply takes time. That corridor from DC to Fredericksburg is a nightmare in the best of weather. There is a lot of traffic on that section of I-95 at any given time. If anyone wants to be upset, be upset with nature. When nature decides to be a b****, we mere mortals can feel pretty helpless.
