Washington D.C., District of Columbia
The drivers were fabulous! They were knowledgeable and entertaining. However, the trolley stops were not clearly marked and as it grew later in the day it become a longer wait for a trolley. One stop by the Jefferson Memorial, after walking quite a distance to the stop, we waited over 30 minutes, just to have a trolley stop that had no room for us. This happened again by the Museum of Natural History.
