The stage

How much time does it take to put the stage together? They will play in Mannheim in the 16th of July and Udine in the next day. I think they need 2 or 3 days for the stage, so that means they have 2 or 3 stages? Is it possible to put the stage together on same day of the concert?

They have more than one stage on tour,I think 3 will be used on the european leg,and it's not possible to put the(Bon Jovi's)stage together in one day. =)
