London is a fabulous city to visit! This journal will not do justice to the experience that I had while visiting. I traveled with a group of people from my high school, so the trip was pre-arranged, and we did most of the standard touristy things that one does while in London. Some of the places we visited were St. Paul's Cathedral, Westminster Abby, Windsor Palace, the Tower of London, and the Globe Theater. While all of these things could be considered to be tourist traps, I still loved visiting each place, and I think that everyone who goes to London should visit each of these places at least once.
Quick Tips:
Probably the most practical advice that I can give someone is to wear comfortable shoes that you don't mind walking in for hours at a time. There were several culture shocks for me when I visited (most of them being good culture shocks), but one thing that I did not realize before traveling to Europe for the first time is that people actually walk to get from place to place (unlike Texas, where I just get in the car and go).
While I personally felt like security was never a huge problem (I never felt threatened or uneasy in London), I do know that pick-pocketing can be a problem in crowded areas, such as the tube (subway). For foreign travelers, it is wise to invest in one of those neck or waist pouches designed for holding passports and traveler's checks. I had one around my neck, and while it was occasionally a pain to deal with, it generally was not a huge annoyance to me.
Best Way To Get Around:
Public transportation is the way to go in London! There are so many choices to meet your needs. Since I had never ridden a subway in my life before visiting London, I loved riding the tube! It was fast, quick, cheap, and easy. Double-decker buses are great for sightseeing within the city. Plus, they are just all-around fun! If you are wanting to travel to other cities within the UK, take the train. Taxis are also littered all throughout the city. These are the best for if you need to get somewhere in the city that is off the beaten path. Taxis are a little bit more expensive than other forms of transportation.
