Hello! It's great to hear that you're planning to visit Munich, Rothenburg Ob Der Tauber, and Bamberg. Here are some insightful travel tips to ensure you have a memorable experience.

Best Time to Visit:
The best time to visit these cities in Germany is during late spring to early autumn (May to September). The weather is warm, making it ideal for sightseeing. The Christmas season, particularly December, is also a delightful time due to the renowned German Christmas markets.

Route and Accessibility:
Fly into Munich, which serves as a great starting point and is serviced by a major international airport. From Munich, you can easily reach Rothenburg Ob Der Tauber and Bamberg by train or car. The train network is reliable and efficient, and driving can provide more scenic routes but may be more costly due to fuel, tolls, and rental prices.

Accommodation and Booking:
There's a wide variety of accommodations, from luxury hotels to budget-friendly guesthouses. It's advisable to book in advance, especially during peak travel season. Websites like Booking.com and Expedia offer many options for all three cities.

Clothing and Essentials:
Pack light, breathable clothing for warm summer months, a good pair of walking shoes and a rain jacket or umbrella as rain can occur. If you travel in the colder months, warm clothing, including a coat, scarf, gloves, and hat, are essential.

Health and Safety:
Germany is, in general, a very safe destination. However, it's always prudent to have complete travel and health insurance. Ensure your vaccinations are up to date and carry essential medication if needed. Also, keep emergency numbers handy.

Local Etiquette and Respect:
Germans value punctuality, privacy and they usually greet each other with a firm handshake. Tipping is customary at around 10-20% in restaurants. Public quiet hours (Ruhezeit) are widely respected between 10PM and 6AM.
