弱弱问一下，伦敦法签是不是不要预定好旅馆的

我从大使馆上看到这段话，不知道是不是不需要预定好旅馆的。不知道具体操作怎么样的。

As the holder of a ’C-Visit’ visa or of a British visa valid for 6 months or less, be advised that there may be a delay of a few weeks for the processing of your application. You will need to apply for your visa in person and will have to produce, in addition to the usual supporting documents, your confirmed return ticket back to your country of residence, a proof of financial means of support (traveller’s cheques) and a self-addressed stamped envelope in order to be informed of the outcome of your visa application. You will also be expected to provide photocopies of your travel document.
