Planning - Sound management at comic con

When filming at the NEC and interviews of cosplayers, one thing to bare in mind is the diegetic sound. Being in a busy location, this may affect the sound quality which means that the cosplayers in the interview may be hard to hear and the footage will be wasted in which this is a big risk as this cannot be refilmed. 

I intend to resolve this issue by filming the cosplayers in a quieter, less noisier location and I will also try to film some of the local Cosplayers at the train station which won't be as loud or busy as it is in an open space, even though there is the risk of trains passing by disrupting interview footage.
