Be prepared for a long day it is worth it.
Started 5.30am finished around 8.30pm. NY Penn station very busy, staff friendly .
Train trip both ways comfortable ,
Washington DC train station has all the facilities you require ie food and bathrooms.
Bus tour : hop on hop off - at your leisure
Hard Rock Cafe
I couldnt fit in as many exhibits as I wanted too , one day is definitely not enough time
Enjoyable day and a must to see if you can spare a full day .
Great trip and really worthwhile doing. Was a very long day we were booked onto the train from NY Penn station at 5:30am and train back was at 19:10pm but despite being really tired we would recommend. Plenty of time to do the whole tour and hop on and off bus to see the sights. We did the White House, Lincoln memorial, Capital Hill, Space museum and Arlington cemetery tour plus plenty of time tor lunch and to be back for the train. Make sure you arrive back at Union St in plenty of time....even though the train was scheduled for 19:10pm, they started lining passengers up to board at around 18:30pm.
