Hi - We would like to visit DC this summer with our two kids ages 10 and 7. I was in DC many many years ago but have no idea how to get around. Where would you recommend to stay without being too expensive. We would pay up to 170.00 per night. We plan on staying two nights arriving on a Friday and going home Sunday. Any suggestion on what to see? I know our son wants to see the memorials. Are they all together? Sorry for so many questions but we are not city people. Any suggestions would be helpful.
