Today was the day with great plan and great expectation. I had secured tickets for the Capitol Hill tour and planned for the evening tour of the monuments from DC by Foot. But things don't work according to plan... We started of early enough (or what we thought..) and hopped on the Yellow line to head to Capitol Hill. Once we arrived at the Visitor Center entrance we found out that there was a long line to go through security. Our tour time was 10:15am and now it's 9:50am. I was hoping that they might be a little bit flexible with time.. Oh.. No.. We missed our ticket time by 5 minutes and there was nothing they can do. If we still want to do the tour, now we had to go wait in the walk-up line that can be anywhere between 30 mins-1 hour wait. So consider yourself warned, if you have your Capitol tour, be early!
Since we didn't have any other big plan till the evening, we decided to wait. Mr. Rojo was an ever loving dad waited in line for us while Miss J and I walked around and checked out the information room. It was a great place to spend time there. There were so many information of the House and the Senate, short movies to tell you about the history and what the Senate and the House do.. We didn't walk around and check out everything. I went back to check on Mr. Rojo and Mr. Z. The line was moving along but it was still a long way to go. So I took them to have a quick snack at the Capitol Hill cafeteria. It was a really nice cafeteria. I would think we probably would enjoy our lunch time there if we had a chance. But before we could even finish our snack, the fire alarm went off!!! We headed to meet up with Mr. Rojo and followed the evacuation route out of the Capitol Hill. So that was pretty much our Captitol Hill experience. :)
Well, it was a nice day so we took our time in front of the Capitol Hill and the Union Station park. Then we headed to the Union Station for lunch. It was crazy busy there. Too many food to pick from... After a fulfilled lunch, we decided to head back to the hotel to take a quick break before heading back to town again for our walking tour.
I found out about DC by Foot tour from the TripAdvisor forum. It was a FREE, tip based walking tour of Washington DC. The tour took us through the heart of National Mall by visiting Washington Monument, World War II Memorial, Vietnam Veterans Memorial Wall, Lincoln Memorial and Korean War Memorial. It was such a great, high energy tour that was full packed with history that won't bore you to sleep. The walk started from the corner of 15th and Constitution Ave. NW and ended at the Lincoln Memorial.
We learned a lot of fun facts like the current Washington Monument wasn't original design. Or if you look closely, you will see 2 different color stone. That's because the construction was stopped for a long period of time before they finished the monument.

One of the highly recommened activity is night tour of the monuments. We didn't plan but by the time the tour ended it was already dark. But the Lincoln Memorial was still packed full of visitors. And it was breathtaking indeed! We just took it all in with all the beauty and sense of pride for the history of this country.
It took us approximately about 2 hours for the whole tour. I highly recommended anyone who will visit DC to check them out. After the tour, we walked through George Washington University to take the Metro back to the hotel. By that time it was already dark but we felt pretty safe walking in DC. It's one of the thing that we really love about DC. It feels very safe to walk around even at night in the downtown area. I'm sure there are certain areas that not safe but as far as the popular tourist places we have no issue there. 
We arrived there right before lunch so we decided to have lunch at McD before we started our journey. The museum is very close to the Harbour so it is an easy walk from the Aquarium. As soon as we walked in, the kids didn't wait to climb on the 3-story playground. It's one of the coolest play structure I have ever seen. There are so many things for them to do.. The structure is made from steel so it looks very artsy and industrial.
At 5 and 7 years old, both of them were big enough to be able to do all the climbing themselves so we didn't have to go in to help them. But for younger kids, parents are welcomed and encouraged to help them out. They ran around all over the place trying out different things ranging from Rock Climbing, Slide, Suspension Bridge, or Tunnel Bridge. They spent a good hour just climbing and then we started to walk around to check out other areas.
There was a gas station and a grocery store that was a big hit for them. Kids can learn to shop for the healthy food and check out at the cashier. They can learn about ATM and gas station. After that, we head up to check out the cookie decorating. Miss J did a really good job on her cookie and Mr. Z did just as well for a 5 years old. :) The finished products were there for long. It was in their tummy right after they finished.
Then we went to check out the Water room. This was probably one of another highlighted room for them. Mr. Z enjoyed playing with the rubber boat and lego boat. Miss J loved to build the dam and see how she could manipulate the water flow. She also did really well with the bubble hoola hoop.
After oh... I don't know.. a really long time, it was time (at least for me and Mr. Rojo) to leave. We had pretty much spent almost 4 hours there. I haven't had much experiences with too many Children's museums but I have to say that the Port Discovery Children's Museum is definitely one of our favorite museum.
Then we headed across the lawn to the
After wandering for a while, it was time for lunch. We headed to the 

We managed to save during our vacation with a great planning this trip. I checked out a few restaurants in the area and was able to purchase $10 certificate from restaurant.com for $0.30 for a couple restaurants. Since we stayed in the normal hotel this time instead of condo or apartment rental, cooking is out of the window. Dining out was planned so that we won't break the bank. There were plenty of cheap eat around town if you know where to look.
