Take your voucher for either a 1- or 2-day Washington DC hop-on hop-off trolley tour to any of the 25 stops and step aboard. Trolleys depart about every 30 minutes and run all day.
Ride along and listen to the onboard commentary, hopping off at any stop to explore further on your own. Through a downloadable foreign language app, commentary is available in Japanese, Chinese, Italian, Portuguese, German, Spanish, and French; earbuds are available for purchase.
Route highlights include the White House, US Capitol, the National Mall, Jefferson Memorial, MLK Memorial, Vietnam Veterans Memorial, and Arlington National Cemetery, which many other tours don't cover.
