Just wait and get money when you get there. The exchange rates are current and you won't end up with a lot of extra money you don't need if you just take out little bits at a time.

I agree about the disposable phone. We did that on our last Paris trip. If you do somehow run up minutes on your own phone, if you have AT&T, they will send you a message and let you retroactively let you buy a fairly cheap package to cover the cost (happened to me in Paris with texting.) I wouldn't recommend using your own phone to make calls...texting is expensive enough, but is fairly inexpensive if you make a mistake.

Just enjoy the trip and don't obsess about all the details. It's not really that difficult to travel internationally. I never get up midflight. I sleep the whole way after the meal. Customs is quicker than you thinks. Then, you are in a whole new country! I leave for Berlin on Saturday for my birthday so I'm super excited. I haven't been to London because it just hasn't worked out. Have a great time!
