It could be? Let's be honest, whatever they do re this they'll get slaughtered for it. If they had holographic signs with actors doing acrobatics in costume next to it then they'd be criticised for favouring guests there over guests at other Disney properties. Nothing there and it's proof it's a failure they're trying to hide. Some will hate whatever they doCould this also be just for the testing? Maybe they are having people park at DS and then take the bus to participate in testing.
