The tram loading zones are open depending on things like staffing and how many trams are in service. The fountain as of late has become a kiddie pool for kids (albeit a very dangerous one because of the water jets) and has drawn quite a crowd of loiterers to it. Sadly they need to put a sign or a fence or something so that little kids don't go playing in it.
While I'm at it, I'm also bothered by the fountain that does nothing more than create a traffic name when heading to/from the tram loading area. To go one step further, I wish the tram loading zone on the north side of the tram zone was always open in the evening time. (the area to the right after you exit the esplanade.)
