Our hotel is in Linthicum Heights. Thursday night we plan to go to the inner harbor for dinner somewhere. Friday we will be in DC all day, hope to visit the zoo, the Air and Space museum, and whatever else we might have time for. Saturday we will be at the virgin festival all day and will probably only get to eat whatever they have inside. Sunday we won't be going till 5pm and therefore we will need to eat lunch somewhere beforehand. I believe we're going to try to make the National Aquarium early that morning. Monday we leave out after breakfast. Any ideas where we can go. Needs to be fairly inexpensive and close to things I've listed. I really appreciate any help I can get, thanks!
