Thanks for asking this question JudyMarie. I purchased Early Entry tics for Munich and Hannover and am hoping that there is a cordoned off front GA area - at all Springsteen concerts in Europe, they have a front pit area for those who queue early or, in some cases, pay for a Golden Circle ticket. It would be unfortunate to be let in early, and then have later comers push forward and crowd you out. Would rather avoid having to fight to keep my spot.
One further question I have is when you actually get let in, and the latest time you need to get into the stadium to ensure you are let in before the GA ticket holders who paid the GA price.
