I love travelling to places without too many bookings. It allows me to make choices on spot. Translates into freedom. But there are some things i also like to prepare for and go. Specially when the new land has a new language.
Learning some key phrases comes in very handy while communicating with locals, shop-owners, asking for direction, etc.
Here is a lovely little video created by Ixigo if you travelling to Hyderabad.
Learn and Enjoy!
