Travelling around a city can be quite expensive. When you factor in the money that you will spend on transport alone, it's already going to take a considerable chunk out of your precious holiday budget. And that's without even considering the price of all the attractions that you want to see.

However, there is a way to save money when travelling to many of Europe's major cities. City cards, like the Berlin Welcome Card, offer discounts and deals on a wide range of experiences including top restaurants, theatre shows, city tours and exciting attractions. What's more, you also receive unlimited, free travel by rail or bus within zones A, B and C for however long the card lasts.

For 2015, we are offering complimentary 3 and 5-day cards to anyone travelling to Berlin. This is already a saving of as much as €39.50 per adult if you were to choose the latter option, and that's before you've even used the card. Along with the travel card, you will receive a detailed map of the city with many of the inclusive attractions marked on it. There's also a guide book telling you all the great discounts you have access to and offering some ideas on how to link them together to form a tour.

So, let's take a look at some of the things you can look forward to enjoying with your free Berlin Welcome Card from Fred..

Berlin Zoo and Aquarium - 25% Off

There are two zoos in Berlin (both of which have discounted prices with the Berlin Welcome Card) but this one is the most expansive. Berlin Zoo has the largest number of species out of any such place in the world and is the oldest zoo in Germany, having been opened in 1844. Animals include many different types of bear (including polar bears), gorillas, king penguins, lions and hippos. There's also a large aquarium on site which can be enjoyed as part of the price. Save yourself €3.25 and take a walk on the wild side.

DDR Museum - 25% Off

In a beautiful location, close to the river Spree, the DDR Museum can show you what it was like to live in the former East Germany. The exhibits encourage you to get hands-on as you learn about day-to-day life in this communist state. Spy on the neighbours as the Stasi did, see original clothing and transport and understand more about the Berlin Wall. The museum receives over half a million visitors every year and you can enjoy it at 25% less than what everyone else pays.

Haus Der 100 Biere and Die Berliner Republik - 25% Off

These two restaurants are the perfect places to enjoy authentic German food and refreshing German brews. Das Haus Der 100 Biere offers one hundred different beers from around the world, with plenty that showcase how good German beer really is. The menu features everything you would expect, such as schnitzel, various different wursts and roast pork. Enjoy 25% off all food and drink with your Berlin Welcome Card.

Die Berliner Republik also has some great food, but the main draw to this restaurant is the beer 'stock market'. Every day, after 5pm, the beer prices get turned on their heads and begin to be determined by demand. Watch the price of your favourite tipple rise and fall on the monitors all around and get ready to order quickly when the price crashes. Receive 25% off main dishes that aren't specials.

Sanssouci Plus - 25% Off

The Sanssouci Plus ticket will give you access to the stunning Sanssouci Palace and many other palaces in Potsdam. Potsdam is situated just outside of Berlin and is linked to the capital by easy rail connections. Incidentally, there is a whole section of your Berlin Welcome Card guide which features a number of attractions in the city for which you also have discounts. Sanssouci Palace is said to rival Versailles in terms of beauty. It too features temples and follies in the gardens and was once the summer residence of the King of Prussia. Enjoy 25% off a Sanssouci Plus ticket which also includes entry to Charlottenhof Palace, New Palace and many more.

Berlin Dungeon - 30% Off

Anybody who has been to the London Dungeons will know what to expect from this attraction. It is perfect for adults and older kids and is a fun way to learn about the gruesome side of Berlin's history. You'll discover the story of ten different Berliners who have made a name for themselves over the years and be dragged into the story at any and every opportunity. Performances are available in English and you can save yourself €6.

This is just the tip of the iceberg when it comes to the savings you can look forward to with the Berlin Welcome Card. Book your Berlin city break with us today.
