Hello! A group of 5 of us are coming from America in July with a 9.5 hour layover in Frankfurt on the way to Turkey. We should arrive at 9:10 a.m. How long does it take to get through customs? Any suggestions on what to do with our luggage in the meantime? Also, are there any foreseeable problems getting back through airport with time, etc.? Do we need a tourist visa to visit the city? It seems from other answered questions that 9.5 hours will be plenty of time to get out and see the city? Any other help is welcomed as well! We are fairly new at traveling so we appreciate any input you guys have. Thanks!
