Build your outdoor entertainment repertoire. Nothing is worse than listening to French Canadians sing bad Beatles songs till 2 in the morning. I know this from experience let me tell you. Build your skills by starting here:
Five minute mysteries: These never last for only five minutes and I think the only reason they are called five minute mysteries is because it takes less than five minutes for the person to tell you them. Basically someone tells you the mystery and then you can ask as many questions as you want but they can only give you yes or no answers. They can become very addictive.
Here is one that I snatched from this great site:
Question: A man lives on the twelfth floor of an apartment building. Every morning he wakes up, gets dressed, eats, goes to the elevator, takes it down to the lobby, and leaves the building for work. In the evening, he goes through the lobby to the elevator, and, if there is someone else in the elevator (or if it was raining that day) he goes back to his floor directly. However, if there is nobody else in the elevator and it hasn't rained, he goes to the 10th floor and walks up two flights of stairs to his room.
Answer: The man is a midget. He can't reach the upper elevator buttons, but he can ask people to push them for him. He can also push them with his umbrella.
