Oh, damn, I'm probably the only person running into a UEFA final
by accident. 
Get-in price on Stubhub is about $2k per person.
We'll probably pass on that one, considering there are six of us and four are not soccer fans.
And good recommendations for a nearby 2- or 3-night stay? We need to be at Madrid airport early Sunday morning to catch a 10AM flight, so has to be reasonably close. Even airport hotels are booked solid. We would probably rent a van unless the train service to MAD is incredibly convenient.
