(UPDATED, 16.21 CET): According to biljettnu.se the audience will be allowed to  enter the event area at 17.00 CET (which either means we’re talking about two different stages or a re-organization of the so far known schedule for this day):

So, we have two different kinds of tickets – concert-only tickets for 650 SEK which can be bought at biljettnu.se  and 3-days-race-tickets including the concert for 850 SEK which can be purchased at theracelegends.com

Then we have a schedule with the stage program starting at noon. Until now many of us didn’t know and wondered how the entrance will be done since the owners of a 3-days-race-ticket can of course join the stage program starting at noon which is also included in the ticket. So as far as I know a lot of fans already bought the full package for 850 SEK just to be sure to stand the closest to the stage.

Thanks to Yana who sent a mail to the CEO we now know that everyone – no matter which ticket for the concert you have – has the same chances to reach the front row:

There will only be one type of ticket to the Roxette concert, regardless of if you have race ticket or a concert ticket.
The stage is located in the event area and there will only be standing tickets. No special tickets for close to the stage are available.
Both those who have a race ticket and those who have a concert ticket only will be forwarded in to the stage area at the same time.

So, the questions change from “how and when do we get in?” to “How does this work when there’s actually artists on stage performing before 17.00? Are there two stages, more entrances? And how do those with the 3-days-ticket get in to enjoy the stage program during the day?
