10C tickets for Paris concert for swap

Widley

Hi, i've got 10c tickets for tonight's Paris concert but my girlfriend is 4 months pregnant and is obviously a little worried about standing for so long and also the potential problem if the crowd gets too excited. Seeing as there is no seating at all with 10c tickets i was wondering if anyone wanted to swap for seated tickets?
i will check any PM in Paris today. I am looking to pick up my tickets around 3.30 and we can just swap the tickets and wristbands then?

thanks for any (late notice) assistance
