You don't know where you are going. We are going to keep the secret till the last minute. We are going to buy your tickets on our own, so that you get to know the destination point only at the airport. What we want is keep you intrigued, so we are asking you to maintain secrecy as well. Turn off the geolocation in social media and do not post any photos that can reveal your whereabouts through geotags or anything else.
