This is the sort of question which can really help you whittle down those early applicants. "I like the Apollo in Manchester because the sloped floor makes me feel drunker and it's close enough to my house to mean I don't have to pay for taxis," is the sort of answer which might suggest they are looking at events from the wrong perspective. Saying something more like, "Colston Hall in Bristol really has the wow factor for visitors since its £20m refurbishment, while the spaces are bright and airy, parking and accessibility are great and the staff make sure everything is streamlined and runs smoothly for event planners," however, might suggest you have somebody more suitable on your hands.
