Understand
This itinerary is written for travelers spending at least a week in Warsaw, however, you can easily pick and choose and customize the itinerary to your own needs and schedule. The itinerary is written to include all the must-see, must-do, must-eat, and must-drink locales, so even if you're time in Warsaw is drastically cut short, you can generally assume no matter which day you come on or follow, you'll at least see some part of Warsaw that's important for any traveler to experience.
Sunday
Morning
Later in the morning, head over to the '''Warsaw Uprising Museum''' in the Wola district. You'll want to save this museum for Sunday because it's free on Sunday, but also, if you get there in time, can attend a Catholic mass at the museum's chapel. You'll probably want to pencil in at least two hours at the museum, although, it's incredibly easily to spend upwards of five or more hours at the museum, especially if you're interested in the Warsaw Uprising. The museum is very well designed and is unlikely to bore anyone.
Afternoon
After the Uprising Museum, you may want to stop by Kultura for a cup of coffee and a bite.
Evening
On Sundays, most stores will close between 6PM and 8PM, though, some brands are brave enough to stay open as late as 9PM. So, if you get back early enough, you can do some shopping. But, if you're in the mood to mingle, especially, if it's during late Spring or Summer, you can grab a seat outside at one of the restaurants at Zlote Tarasy in the center and relax over a meal. Party-wise, things will be much tamer than Wednesday, Thursday, Friday, or Sunday, but you should be able to find some party at most clubs.

Next, head over to the Wilanow Palace, which is now an art museum. On Sunday, entrance is free and the museum is open from 10:30AM until 6PM with last admission at 5PM. The palace gardens would be a great way to kill time with a significant other too. The park that the palace is located in is open until dusk.

Saturday, like most everywhere else on Earth, is a great night to party in Warsaw. There are several impressive clubs that exceed expectations for most Saturday nights. Kulturalna, though, not a club, will be a lively place most Saturdays and a good place to kick back and listen to a wide variety of possible beats.
Don't worry too much about how late you stay out if you're partying somewhere along the metro line, because, like Friday, the metro runs until 3AM and opens back up two hours later.
