Hi
its good to see that people are able to find some time out their busy schedule for themselves otherwise they generally don’t even think of going on trip. Yes you can have trip of 3 days during which you can visit most of the important places in Washington City. You can find tour packages online from a large no of tour operator in the city. But go for which provide the cheap and best thing according to your budget. You should try to arrange trip during weekend so that your work will not suffer because of this. I generally use Tours4fun services for any trip in USA as they provide the best tour packages at very low prices. To know more about their current offerings, you can visit to tours4fun.com. You can also get online help from their consultant who will definitely eliminate any confusion of yours if any. I really enjoyed the accommodation and transportation services they provide. Moreover the stuff works very hard to give their best to the entire tourist group. I think you should go once for their services and you definitely will not be disappointed.
