In DC Week of Thanksgiving with spouse and kids 10 and 12. I have narrowed my hotel search down to the following: St Gregory Suites, One Washington Circle, Marriott Key Bridge or Hilton Garden Inn/Arlington Courthouse. Has anyone every stayed in these places tha can offer some advice? How long does it take to get from HGI to Washington Monument? Want place close to metro, walking distance to choice of restaurants and with room space to lounge around. Help me choose. Thanks!
