For me, cheapest is where I am right now, in Riga, Latvia; about US$1 an hour. Most expensive I think was 8 euros (approx US$16 I think) in Milan, Italy. Suffice to say, I didn't stay there long.
2. For the girls: Is there any way to make your period come sooner (just by a few days)? Mine's due to start mid-week next week, and I'd like it to start on Monday.
3. Another travelling question. Boxes of chocolates - best to go in carry-on or checked baggage (suitcase), when flying across Europe, and then a Trans-Atlantic flight?
