I am travelling to DC for 6 days in April with husband and kids ages 14 and 16. It is our first visit and we plan to hit all the usual highlights: monuments, museums, etc. I have narrowed my choices to the following and would like some feedback if possible. 1) Topaz in Dupont curcle ($250 per night, 2 free breakfasts, 2 at $12 each), 2) Hampton Inn Convention Center ($239 per night, free breakfast), and 3) Courtyard by Marriott Convention Center ($279/night, no free breakfast). All are queen, queen rooms. We don't mind walking, but will certainly take Metro places as well. Any thoughts from the experts out there?
