Twenty One Pilots fans better get ready for a longer-than-expected stay this weekend at Amalie Arena.

Days before the alternative duo's extremely sold-out concert at Amalie Arena in Tampa, the venue has reversed its announced policy on pre-show campouts and queues, and nixed plans for a first-of-its-kind line lottery for general admission floor access.

The policies had been announced Oct. 19 to ensure fan safety around the arena, where there's lots of construction. But on Tuesday, Amalie announced that "after working with our partners around the arena," fans will be allowed to camp out or line up early, eliminating the need for a line lottery.

Here's what fans coming Saturday need to know.

Early lines will be allowed. Fans can arrive as early as 9 a.m. Friday and set up in the Green Lot at the corner of Jefferson Street and Channelside Drive. (Technically it can only be a line, as city ordinances still prevent camping out, but do what you have to do.) That line will move to the plaza outside the arena sometime midday on Saturday, after the completion of the Walk to End Alzheimer's at 9 a.m.

There will be no lottery. Because the floor is open general admission seating, the arena had to institute a lottery to figure out a way to have those fans line up safely — hence the lottery. Since the early line is no longer a problem, the line lottery will no longer be needed.

Twenty One Pilots fans on Twitter were relieved to hear the news, even if a few were miffed by the relatively last-minute notice.

You cant just keep changing plans and not giving us a heads up, you gave no inclination of the lottery being able to be changed and now everyone has made plans & now you changed it again, whos gonna pay me back my $35 for the concert ticket i bought this for a show friday since-> — SHELovelyLittleLonelY 10/13 (@Shellbo6987) October 30, 2018
