Flights and hotel booked directly after the draw. No problem to get a ticket on the day of the match. Maybe in the Barca end, but who cares? Went to Nou Camp with Schalke in the Quarter Final 2008. So I can tell you, who wants to come in, will come in. If you got your nerves under control, it could be cheaper as you think;-) close to kick off is the time to buy.
