With fares of $268 r/t, a weekend in Cologne, Germany seemed like a pretty good idea. The fact that they have lots of beer there didn't hurt the decision process.
Clearing customs & immigration at CGN airport was a 10 minute affair. I highly recommend it for European connections, especially to LCCs, if you're in the neighborhood. Shortly after that we were on the S13 to downtown and then the Dom.
It is a pretty impressive church, inside and out.
We also happened upon a wedding on Saturday morning; Organ Grinder and everything.
