Does the venue cater for visitors of all physical abilities? If not, can visitors still engage somehow?
Does the new experience enhance other elements of the visit, and the broader relationship with the museum?
Is the venue an inherently noisy or otherwise distracting environment?
Does the experience rely on funding? How long will that funding last?
Will visitors create and/or contribute content? Is there a licensing agreement in place to allow you to use it legally?
Will members of a group interact at their own pace? What happens to the group if they do?
Are visitors told what to do? Is it reasonable to expect visitors to follow those rules?
