Just a quick update.  If you think there are more tourists now than ever, you're right.  More than one billion people visit another country each year.  The U.N's World Tourism Organization expects the number of international tourists this year to break 2013's record of 1.1 billion travelers.  That number topped the year before that and so on.  It is only greatly increasing annually.  At this point the guess by the U.N's World Tourism Organization is that 40 to 50 billion people will travel this year.  That only means you should prepare your traveling trips more carefully and effectively and inform yourself on safety tips and rules to wherever you travel.
