Im going to Edinburgh this weekend to do a ghost hunt at Edinburgh vaults. I am just wondering has anybody been and if so what was the best part of the vaults. Nidry street or Sibsy street? Due to health and safety when we are put into groups we then have to chose which street to go down cos this is the street we will be staying untill it ends. So if anyone could tell me what they found the best i would be most grateful.
