Advice on a trip to an amusement park in Poland.

From September 5 to 11, two friends (both 18 years old and from Belgium) and I are planning a trip to Poland to visit some amusement parks. Here’s our current itinerary

September 5: Land in Krakow at 9:30 a.m. Take the train to Katowice and visit a coal mine in the afternoon. On the second day, we’ll visit Legendia, and once we’re done there, we’ll explore Katowice before taking public transportation to Zator. We’ll spend the next 4 nights at Western Camp in a teepee tent. The next two days we’ll visit Energylandia, and on the third day we plan to visit Energylandia again as well as the water park (using the same tickets). The following morning, we’ll continue on to visit Auschwitz, then head to Krakow to explore the city a bit and spend the night there. The next day, we’ll spend some more time in Krakow before flying back at 5 p.m.

Does anyone have any tips or suggestions on what to do differently?
