A few pertanyaan about Heidi and the Volturi

1. In New Moon, it's explained how the Volturi don't feed from Volterra's population, because their coven and guard is so large that the number of missing/dead people would be noticeable. They feed off tourists instead. But wouldn't the human population notice large groups of tourists vanishing too? Wouldn't that deter people from going on holiday there?

2. When Heidi appeared she was leading a group of tourists to the Volturi, like she'd pretended to be a tour guide. But the way her outfit was described, it'd make lebih sense that she'd be luring young men one oleh one, atau pretending to be a prostitute. Why was her outfit like that? An entire tour group wouldn't need to be physically attracted to her to follow her.

3. I also think Heidi's tights were described as fishnet ones (obviously a pun on her being the "fisher"). Fishnet tights have holes in them, which is what gives them their name. Wouldn't those holes expose her skin, which'd shine in the bright Italian sunlight?
