When visiting Hannover, it's helpful to know that WLAN is available at the Central Station and in several cafes, such as Art Oase and Depot Cafe & Bar, where you can enjoy free Wi-Fi. If you prefer a more dedicated internet experience, there are internet cafés in the Steintor area, but remember to register with your passport. For getting around, consider purchasing the Hannover Card from the Tourism Office, which provides free public transportation and discounts at local attractions. Public transport tickets are categorized into single-use tickets and subscription-based cards, with a 1-zone ticket typically sufficient for most city travel. If you're planning to explore the region, look into weekend tickets for regional trains, which offer great value for group travel. Lastly, be aware of local customs: tipping is not compulsory, but rounding up your bill or leaving about 10% in restaurants is appreciated. Also, paying individually is common in smaller eateries. Don't forget to bring a power adapter for your devices, as the outlets in Hannover are standard European types C and F, operating at 230V. These tips will help you navigate Hannover smoothly and enjoy your stay.
