I don't think Kosovo could have been visited due to the violence and dispute with Serbia. Also Bratislava maybe close to Vienna for air transport but they do have their own int'l airport for the record. And the tiny principalities could work due to the Vatican City being in Rome; San Marino close to Tuscany and Venice; Andorra being near Toulouse; Liechtenstein is near Zurich; and Monaco is right next to Nice. Also the Balaeric Islands (Palma de Mallorca), Azores, Canary Islands, Greek Isles could also work due to the connections through Madrid, Barcelona, Lisbon, and Athens. Plus one more thing is that maybe to my guess after South America they could have gone Africa (2 Legs), SE Europe or the Middle East (1 Leg) and SE Asia (1 Leg) until continuing on to Penang and so on. The leg before Penang could be either be in Kuala Lumpur (obvious) or Indonesia (Sumatra, Java, or Bali). If they did do a leg in Kuala Lumpur, I hope they visited the Ginteng Highlands. Plus maybe for a roadblock, speedbump, or fastforward I like to see a team eat a Durian fruit due to its unusual smell and taste. (Durian fruit idea is from Travel channel's Bizzarre Foods)
