And, what UK-specific travel tips might you have?
Mind the gap.
(You will understand when you are there)
Some more serious things:
- Keep in mind that the cars drive on the left side. I nearly got driven over on my first day.
- Forget using the bus or taxis, sorry, cabs in the central area. The streets are much too choked for that and the bus stops are so close together that you can walk.
- When you want to visit Tussauds and go there by subway, do not take the first entrance you come across but keep walking to the next corner of the building. That one is for single persons and overlooked by most tourists resulting in a short queue.
- The beefeater tour at the tower is good.
- Don't forget about this new Shard thing when you use an older travel guide.
- Use a travel guide btw.
- Remember the stereotype of how Brits always form orderly lines? Forget it.
- After the flight you will have a bad jetlack. Try to adapt your sleeping schedule to GMT before the flight if possible
- Visit the Royal Observatory
- You won't find any original British food in central London anywhere. Good for your taste buds, bad if you want to try out if it is really that bad.
- When you are only used to planned US cities always have a navigation app or city map with you.
- Pray that they have renovated Heathrow and it isn't as confusing and time consuming then when I visited.
- Do not take the North/South line when there is a soccer or cricket game on the same day.
- Huge IMAX cinema.
-If you are into it you can visit all that Harry Potter locations (train station etc.)
Things not to do (not to take serious. At least not much):
- Make fun of soccer
- Compare soccer to football with the conclusion that it is inferior
- Mention that in international cups the Brits lost horribly for the last 4 years especially against Germany.
