Did you know you could see a shark feeding in Washington? You can also see an octopus, a rare albino alligator, and poison frogs. And we must not forget about piranhas, which by the way, are not as ferocious as they're portrayed in Hollywood.

The National Aquarium in Washington is in the heart of some of the city's main attractions, but often gets forgotten or overlooked. It's definitely worth a trip.

Groupon is selling tickets to the International Spy Museum for $10 a piece until the end of the weekend. Entry to the museum is usually $21, so it's definitely a good value. The only catch is that the ticket has to be used by March 23, 2012, which makes it hard if your trip to the nation's capital is planned for Summer.

But no matter when you're coming, it's worth it to sign up for a daily deals service like Groupon or LivingSocial for Washington. They often have discounts on popular tourist attractions and restaurants.
