Thank-you for the suggestions. I checked with the hotel and there should be no problem parking, then as suggested taking the metro. The system looks as though it is designed the same as Boston's-colorcoded and easy to navigate. Although from what I understand much cleaner than ours!After reading through previous posts, we have decided to forgo the Washinton Mnt. ascent and go with the alternative Old Post Office Square Pavillion. Still deciding between Night Tour Trolley vs. walking ourselves-but either way should be beautiful. Thank-you to all the local experts who take the time and energy to respond to all of us out-of-towners. Sometimes going through all the tourbooks and coming up with a plan of action, especailly with a city with so many options can be overwhelming and time consuming. Your insights and recommendations are most appreciated. Looking forward to exploring your beautiful city. On a side note-I'm hoping to go for an early morning run-are there certain areas better than others? Is there particular ettiqiute(similar to the commuter/escaltor variety) I should be aware of? Thanks again.
