美国首都有啥值得去的景点？哪些景点要预定？还有想问一下哪里可以买到白宫的蓝卡参观券？
华盛顿纪念碑
登顶可以提前30天或1天买票。当天一大早还有机会现场买票
Walk Up Tickets (Same Day Only)
- The Washington Monument Lodge, located along 15th Street between Madison and Jefferson drives, opens at 8:45 a.m. for distribution of free, same day, timed tickets on a first-come, first-serve basis. One person may obtain up to six tickets as well as request their preferred ticket time. All visitors (including children ages 2+) must have a ticket to enter the Washington Monument. During peak season, tickets run out quickly. Be advised that many visitors form a line to wait long before the ticket window opens.
Online Advance Tickets
- 30 Day Advance Reservations - Order tickets online up to a month in advance of your visit. Inventory for the next available day (30 days out) becomes available at 10 a.m. each morning (e.g. - on May 7 at 10 a.m., tickets will become available for visits on June 6).
- 24-Hour Advance Reservations - Didn’t get tickets in advance or planning a last minute visit? A limited number of additional tickets are made available at 10 a.m. each day for the next day’s visits (e.g. - on May 7 at 10 a.m., tickets will become available for visits on May 8).
Both 30 Day Advance and 24 Hour Advance reservations may be made at recreation.gov or by calling 877-444-6777. Though there is no admission fee for the Washington Monument, there is a $1.00 service charge per ticket to cover reservation service; these fees are NON-REFUNDABLE. Ticket availability is limited and all tickets for a given day are often reserved the day they become available.
Group Tickets (Online Only)
- Groups may reserve up to 55 tickets up to 30 days in advance at recreation.gov ONLY. No walk ups are available for group tours. There is a $1.00 service charge per ticket to cover the reservation service.
非裔美国人历史和文化国家博物馆
NMAAHC 也可以提前30天买票预约。当天和近期有可能有票，有可能没票

这是美国政治正确的中心，一定要去看看，有句话叫知己知彼才能百战百胜

楼上怎么这么多高堡奇人 
那个角度可以免费在上面看呀
白宫参观需要找议员提前几个月预约，而且无法保证预约时间，会让你提交两个你希望的时间。
DC 有很多免费的博物馆，航空航天博物馆预约一下等待时间短一点。

如果去那些Smithsonian 博物馆要寄存backpack 吗？我们是去旅游，一般会把午饭面包放在背包里的。我就担心有背包不让我们进去。我们也没私家车放背包呢?不行的话，我们就打算带女生那种handbag?
白宫
打电话给oval office要
在DC河对岸住了十年的表示，真没啥好玩的，可能我不爱逛博物馆，进城基本只有以前偶尔会去看一下奇才的球
住nyc河对岸的表示，nyc也真没啥好玩的 
每次别人让我推荐我只有尬住+法拉盛一条龙
