We recommend that you get a hotel near Warsaw's city center or closer to the city of Józefów. If you need to be close to the venue, then you can also look for a hotel in the city of Marki, but options are more limited.
We are working on it and will add more details in the near future.
Wear what makes you feel most comfortable (except for a white dress). We suggest long or short dresses for women and suits for men. August is a hot month in Warsaw, and relatively dry, so wear something breathable.
The ceremony will be outside. The reception will be mainly indoors, but the exeternal area will also be open.
Walk through the parks and see the huge Chopin statue. Eat traditional Polish food at a Milk Bar. Visit a Food Hall for nice beer and food. Do a Free Walking Tour to soak in some history. Walk alongside the Vistula River. Visit the Palace of Culture and Science (go to the top for a nice view of the city). Visit the Neon Museum.
