You're talking yourself out of a calm position. Don't give up!
UEFA will pay a fee to rent the stadium but will keep all the ticket money, so the only way it's worthwhile for Portugal is to let us be tourists and boost their economy.
The local bars, restaurants, and hotels will kick off if they don't get a slice of the pie.
I'm absolutely convinced both clubs will go back and explain its just not possible for them to lay on anything remotely close to 30+ planes too.
Sense will prevail (because there's money at stake before anyone responds "not if UEFAs involved")
