How was your experience?
Operator buses customers through major landmarks & attractions in central Washington DC. The sights are spread across 4 loops. Each of the 3 loops this customer took lasted roughly 2 hours without getting off at any stop. At some sights it is possible to transfer loops. Buses have an open top deck with an enclosed lower deck which is air conditioned. The driver plays a pre-recorded commentary. Bus frequency appears to be 15-20 minutes. It is therefore easy to leave the tour and explore independently and then resume on a following bus on the same tour or find a transfer point to resume on a different tour. Staff were helpful and buses comfortable and uncrowded. The tours are useful for becoming familiar with the city's layout and attractions. A notepad might be useful to list sights for further exploration.
