Liberty has been the best for park in the past few years if you're looking for the 2 hour range. In the past few years they've done a good job at taking care of their parks and maintaining them.
Whitetail's park in the past hasn't been the best, but like they all said, Whitetail got a new park manager so hopefully it'll improve this year and in years to come, and they are putting in a new lift for the park which will be really nice. It's also really close.
Liberty and Whitetail are the closest. Traffic on 495 flies if you catch it at the right time of day. I think I've hit 85 on the beltway and 270 and I was even with traffic/getting passed here and there, just look out for cops and crazy drivers if the traffic is going that fast. You can also get slow days too though, it depends on the time of day and day of week, I think timing for us has ranged from 1 hour and 15 min to 3 hours.
Springs is pretty sick, I'm on the VA side, and its about 4 hours from my place, but the parks are better than liberty/whitetail.
Massanutten has had a legit park when I have gone there, but I haven't been in a few years. Its about 2 hours from DC.
Snowshoe is about 4 hours I think from the Va side of DC, and its pretty legit. The parks last year could have used some work, but they were still pretty good at times. They needed to work some on maintaining the jumps, they'd get divits and uneven patches on a lot of the lips which can throw you off, For example, I would go off a jump once and there would be a divit that I would catch an edge on, so the next time I'd go off to the side of it and the jump was lopsided so It'd pop u up a lot more than the other side, or I couldn't get enough air to clear it. But its easy to adjust to it.
