According to forum posts, the road quality in Poland is generally good, especially on main routes between cities, which are described as wide and well maintained. However, some single-lane main roads might be narrower than expected.

Travelers have noted that Polish driving rules include driving on the right side of the road, mandatory use of seatbelts, and the requirement to have headlights on all year. Using a phone while driving is prohibited, and strict penalties apply for drinking and driving.

It's suggested by some users to use Google Maps for navigation as it is reliable in Poland. While the roads are good, travelers mentioned that construction work can cause delays, particularly on routes like the A1. Signage is generally clear, making it easier for non-Polish speakers to navigate.

For those planning extensive driving, such as visiting multiple cities or historical sites, forum contributors recommend planning routes carefully to avoid traffic and construction areas, possibly adjusting travel times to less busy periods.

According to forum posts, the most comfortable and recommended train service for traveling between Warsaw and Krakow is the InterCity EIP train. These are high-speed trains known for efficiency and comfort.

Some travelers mentioned that first-class tickets on these trains offer more space and include a small meal and two drinks. However, opinions vary on whether the first-class service is worth the extra cost, as the difference in comfort compared to second class is minimal. Booking tickets 30 days in advance is advised for better prices, and prices can vary depending on the time of day.

Travelers can book tickets through the official Intercity PL website (https://www.intercity.pl/en/). This site is frequently recommended for its reliability in providing ticket services for these routes.

Some travelers have suggested that flying into Krakow and then arranging a door-to-door transfer through a tour operator, which includes an entry pass to Auschwitz, is an easy option. This method handles both the flight and local transfer seamlessly.

According to forum posts, another popular way to reach Auschwitz from Krakow is by taking the Lajkonik bus service, which terminates directly at the museum gate and costs 15 PLN. Alternatively, travelers can take a train from Kraków Główny to Oświęcim for 9 PLN and then a taxi to the museum.

For those preferring to drive, rental companies generally allow crossing into neighboring countries like the Czech Republic for a fee, enhancing connectivity to places like Auschwitz from different locations. Public buses also connect various cities to Auschwitz, and details on these services are often discussed in travel forums for planning purposes.

According to forum posts, some of the most reputable car rental companies in Poland include Sixt, Hertz, Avis, Europcar, and Panek. Travelers have specifically recommended Panek and Hertz for their services.

For many users, one-way rentals are possible within Poland, such as from Krakow to Gdansk, and even internationally from Warsaw to Tallinn, although the latter can be quite costly. Some travelers said they paid around $1,700 USD for a one-week rental including a hefty one-way fee. There is caution advised against renting EVs due to limited charging infrastructure.

Travelers have called out that renting a car in Poland follows similar procedures to other EU and North American countries. Car rental terms and conditions do not specify an upper age limit as long as the driver has held a valid license for at least one year. Concerns about reading road signage in Polish were noted by some visitors, though others mentioned that navigation apps could mitigate this issue.

According to forum posts, Krakow offers a variety of dining options that cater to different tastes and budgets.

For a unique dining experience, travelers have called out Klezmer Hois, which presumably offers a cultural touch to its dining experience. Additionally, places like Paul’s Place were mentioned for their offerings.

It's noted by some users that popular spots like Morskie Oko require reservations in advance due to their popularity and outstanding food quality. This suggests planning ahead to secure a spot at favored restaurants.

According to forum posts, Christmas markets are a popular holiday activity in Poland, particularly in cities like Wrocław, Gdańsk, and Kraków. These markets attract visitors with their vibrant atmosphere, unique gifts, and traditional food items.

Some travelers expressed interest in experiencing traditional Polish celebrations such as All Saints Day, where people visit cemeteries to light candles and bring flowers to commemorate loved ones. This event is highlighted as a significant cultural experience rather than just a public holiday.
