You should have been there

Hear from listeners about the views that have inspired them and created travel memories both happy and sad. With special thanks to Julia Lo Bue-Said of The Advantage Travel Partnership, James Beagrie of Meon Valley Travel, Mary Poulton, Rebecca Halpern and everyone else who got in touch to share their rooms and their views via our twitter account, @youshouldhave BT 

Bats, birds and bones, not to mention churches and cheese. We enter the twilight zone of caverns and grottoes to discover much more than stalactites and stalagmites.

We discover ways of adding spice to your travels by undertaking special or unusual quests.  The "route of the dovecotes" in southern France, the grounded solar system in Zagreb and the Shakespeare trail in Stratford-upon-Avon are all on the itinerary. Thanks to Norman Smith, Tim Neale and Gary Knapper for taking part.     

Simon takes the temperature of travel in Estonia, Latvia and Lithuania, three small states in the menacing shadow of Russia and Belarus. Even so, he enjoys the scenery, the hospitality and a surreal cultural tour in the Estonian town of Sillamäe. With thanks to his guide, Valentina, and the anti-war protestors of Tallinn. 

We discuss the real value of travelling with the help of listeners' descriptions of their most expensive holidays. But were these the most enjoyable ones? With special thanks to Jan Morris and Susan Latham 

We discuss how drugs have influenced travel and tourism: Amsterdam, L.A, the Hippy Trail, the Green Tortoise and more recently, Breaking Bad and Ozark. Plus a health warning about medicines that are considered illegal drugs in some parts of the world. Many thanks to Tony Wheeler, co-founder of Lonely Planet publications, for his contribution. 

We unpack the perennial travel problem of the incredible shrinking baggage allowance, with the help of listeners, previous contributors and the surrealist maestro, Marcel Duchamp. Thanks also to Rebecca Halpern, Sascha Heeney, Sarah Baxter and Tristan Gooley.  

We ponder the possible consequences of Putin's brutal war for travel and tourism, helped by Russian travel expert, Neil Taylor. Are there any parallels to be drawn with apartheid South Africa or Franco's Spain? And Simon recalls his recent visit to Chernobyl when it was, hard to believe now , a tourist attraction

We discover what awaits visitors to the first truly post-modern World Cup. As stadiums rise from the desert, Doha's beautiful new museum opens its doors to Simon, if he can manage to find the way in!  With thanks to Samuel and Daniel for joining in. 

Simon goes to Sydney, newly-opened to the world and, of course, eager to welcome tourists. He gets free vegemite at the airport, roams the city to discover what is and isn't open yet and enjoys some of the city's simpler pleasures: a tram ride, a sunset walk across the iconic bridge and a trek through the Sydney Harbour National Park, where the suburbs, the sea and the outback meet. Thanks to Jane and Jim O'Donnell for taking part.
