One potential problem with that location... the windows are going to provide a lot of backlighting at that time of day. Pictures taken towards the windows, from the direction of the space in front of the fountains, are likely to result in photos where the costumes are shadowed and hard to see, maybe even silohuetted completely. Which can be a fun effect, but if you want to see costume details, we'd want to shoot pics somewhere else where there won't be a bunch of bright light behind the cosplayers too.
Unless the photographers are supposed to stand against the windows and the cosplayers have their backs to the fountain? Not sure there's enough room for that...
