英国短期旅行签证类型问题！

刚在UK visa 网站上注册就有要选签证类型，Visa type & Travel Purpose：Student、Transit、Other Non-Settlement、Family Visitor (>6 months)、Family Visitor (<6 months)、Settlement、Visitor (>6 months)、Visitor (<6 months)、Tier 1、Tier 2、Tier 4、Tier 5，有这么多种，该选哪一个？选了Visitor (<6 months)，结果点开的解释是If you are wanting to come and do business in the UK for a short time. This includes academic visitors, visiting professors, overseas news media representatives and film crews on location. 又好像不包括旅游，就迷茫了，求指点！另：我是在西班牙留学想去英国玩，所以会在马德里申请签证。
