Hi Lan The traditional Grand Tour was something that wealthy people did in the 18th and 19th centuries, so they're probably not on iTalki to tell you about their experiences!! Nowadays, in the UK, it is more likely that students will take a 'gap year' holiday instead, usually between high school and university. They will use this to visit other countries or do charity work, or both, in order to expand their horizons and enrich their lives with new experiences ( or just get drunk ;p )
