The country which you get addicted to. And when you come back home, you buy wine only produced in New Zealand, because you believe it's the best:)
A week living on a sailing boat. Amazing sunsets. Lying on the wild greek island coast while watching the starts and drinking wine. Chilling and reading a book while the boat is sailing, partying and laughing after it stops in the evening. It's very worth to try it - memories for the rest of your life guaranteed:)
