You need a valid passport and credit card linked to that name so they can use it as a guarantee if they return cash to you. We did not know this and filled out the receipt/tax refund form with my name - however I did not bring a credit card to Europe, so we had to go all the way back to the store to reprint the receipt. We were 30min late for gathering at that point! Also another thing to note is that, if you fill up your credit card details at the bottom of the form, you will be ineligible for the cash refund (that is on the spot), and the only way would be a refund to your credit card after you submit the form at the airport. Well, it has been 1.5 months and the refund has yet to be credited to the card! So if you're thinking of going shopping in Europe, opt for the cash during the tax returns if you can.

Schönbrunn Palace (German: Schloss Schönbrunn [ʃøːnˈbʁʊn]) is a former imperial summer residence located in Vienna, Austria. The 1,441-room Baroque palace is one of the most important architectural, cultural, and historical monuments in the country. Since the mid-1950s it has been a major tourist attraction. The history of the palace and its vast gardens spans over 300 years, reflecting the changing tastes, interests, and aspirations of successive Habsburg monarchs.

Franz Joseph I or Francis Joseph I (18 August 1830 – 21 November 1916) was Emperor of Austria and King of Hungary, Croatia and Bohemia from 2 December 1848 until his death on 21 November 1916. He was born in this Palace. 

He was the longest-reigning Emperor of Austria and King of Hungary, as well as the third longest-reigning monarch of any country in European history, after Louis XIV of France and Johann II of Liechtenstein.

The Belvedere is a historic building complex in Vienna, Austria, consisting of two Baroque palaces (the Upper and Lower Belvedere), the Orangery, and the Palace Stables. The buildings are set in a Baroque park landscape in the third district of the city, on the south-eastern edge of its centre. It houses the Belvedere museum. The grounds are set on a gentle gradient and include decorative tiered fountains and cascades, Baroque sculptures, and majestic wrought iron gates. The Baroque palace complex was built as a summer residence for Prince Eugene of Savoy.

St. Stephen's Cathedral - current Romanesque and Gothic form of the cathedral, seen today in the Stephansplatz, was largely initiated by Duke Rudolf IV (1339–1365). The most important religious building in Vienna, St. Stephen's Cathedral has borne witness to many important events in Habsburg and Austrian history and has, with its multi-coloured tile roof, become one of the city's most recognizable symbols.

Built by prince-archbishop  Wolf Dietrich von Raitenau in 1606 as a token of his love for Salome Alt. Originally known as Schloss Altenau, it would subsequently be renamed “Mirabell” by Markus Sitticus.  

Mirabell is a female name form Italy, a compound of the words mirabile ‘admirable‘ and bella ‘beautiful‘. And Schloss Mirabell, with its glorious gardens, has clearly earned that name beyond a shadow of a doubt.

In 1854, Emperor Franz Joseph made Mirabell Gardens open to the public for the very first time. To this very day, it remains a gem of garden architecture and a popular photo motif.

Salzburg Cathedral (German: Salzburger Dom) is the seventeenth-century Baroque cathedral of the Roman Catholic Archdiocese of Salzburg in the city of Salzburg, Austria, dedicated to Saint Rupert and Saint Vergilius.

The palace was intended as a personal refuge for the reclusive king, but it was opened to the paying public immediately after his death in 1886. The palace has appeared prominently in several movies such as Chitty Chitty Bang Bang and The Great Escape and serves as the inspiration for Disneyland's Sleeping Beauty Castle and later, similar structures.
