20. The Vatican
Although the Vatican can be a great place to visit, the wait isn’t worth it. With millions of people visiting every year, you must have everything planned and paid for in advance if you even want to get inside. You have to get there very early in the morning to stand in line for a long time before seeing the interior. Moreover, because of the sweltering summer heat, don’t expect that you can dress down to keep cool. There is a stringent dress code on what you should wear in The Vatican, which boils down to covered shoulders and knees. Don’t plan to go on weekends either, as The Vatican and its museums are closed on Sundays.
