As the only city located on two continents (Europe and Asia), you could say Istanbul is double the fun. The attractions of this city are endless: Topkapi Palace, Blue Mosque, Hagia Sophia, Galata bridge and tower, Taksim Square, Grand Bazaar, Basilica Cistern, and the Maiden's Tower are a great way to get started to discovering the identity of this amazing city.

Known for it's cheap beer and destination for stag and hen do's, there is much more to this Central European capital. The main sites like the Lennon Wall, Prague Castle, Charles Bridge, and Old Town Square are a must see. Do yourself a favour though and try to get off the beaten path and check out places like the Kafka Museum, Rigierovy sady park, and St. Vitus Cathedral.

This is a capital like no other. It's mainly known as the home of the Hungarian Parliament Building, the Sziget Festival, and the Széchenyi Baths. Make sure you carve out time to see sights on both sides of the river like Heroes Square, Vajdahunyad Castle, Chain Bridge, Fisherman's Bastion, Shoes on the Danube, and Buda Castle.

Venice may be a victim of overtourism and climate change, but there is still time to see this Italian island while contributing to its longevity. Stay a few nights here, grab some gelato and pizza, and check out the Rialto and L'Accademia Bridges, St. Mark's Square with the Campanile, Doge's Palace, and Bridge of Sighs in the distance, and the neighboring islands of Lido, Murano, and Burano.
