I'm booking a flight from EWR to MUC and all my options have a 4 hour layover at either LHR, FRA, TXL, HAM, or GVA.
Which would be the best for my layover (morning until afternoon)?
I will have two small children in tow (9 and 6). I was considering FRA since it would give the longest overnight leg for us to sleep, but am interested in what the other airports might have to offer. I will also have access to the Star Alliance lounge.
