My brother in law and I want to take a long weekend in Europe someplace. He's coming from SFO or LAX on BA using miles and I'm coming from DEN on *A paying. We originally thought LHR, but both want to go someplace new. Any recommendations? We would like to see some sights do tourist stuff, but mostly hang out in a new city drinking and eating the local fare. We're leaning toward VIE, but are very open to ideas.
