My boss and I have a meeting in Leesburg, VA at the end of the month. We're going to go a day and a half early because she has never been to DC and she wants to see some of the monuments and maybe a museum. Any recommendations for hop on hop off tour lines? TIA.
We did Old Town Trolley when DH and I went in February and had no complaints. The guides were very fun and informative and it takes you to all the must see spots.
If you will be in Leesburg anyway I recommend stopping at the Udvay-Hazy air and space museum. It is out near the Dulles Airport and I think it is so much better than the air and space museum on the mall.
