意大利签证问题需要帮助

我发email去意大利使馆要预约，使馆回道：
You do not need to make an appointment in advance, you can submit to Italy application centre directly. However, there is alright to have someone else submit the requirements but the applicant needs to be interviewed personally for several applications.

让我很纳闷，大家不都是去预约然后面试的么， 怎么感觉现在不是这样的啊，我比较纳闷而已，按这种说法，别人帮忙递也OK而且不是都需要面试？现在迷茫中，大家帮忙看一下啊

并且机票跟hotel都是book而已，没有真的给钱，没关系吧

有人知道北京哪里买保险比较好么？
