2. Don’t Fly by the Seat of your Pants
Take the time to really consider what you want to see and do while you’re in the city. Don’t try to see and do too much, obviously, but you should absolutely do some research before you travel to the city. Do you want to hunt down a TARDIS? Do you want to see Big Ben? It’s important to plan ahead and make sure you’re seeing the sites you need to see in the most efficient order.
