We will find out for sure in a few weeks here, you ask some CMs and you are told no, all viewing will be only for those that have tickets, except the first weekend and you ask others and they say it will work the same way as always, that the seats will be for those that have tickets and the standing will be available on a first come, first serve basis.
Since this is the first year that they have done anything like this, no one will know for sure until the first Monday that it runs.
My guess would be that standing will be available, but if it is anything like normal, you may need to arrive by noon, at the latest to get a good spot. As for where to stand, just make sure you are within the ropes that might be setup and that you have a clear view of the stage that will be setup.
