I agree with this assessment. Gee, I was there twice in December from the US and it was a challenge to just get to the right exit to the Frankfurt hotel where we were staying overnight. Also, on the return to the US, both visits, I had to ask for assistance to get to the right area. As an earlier poster stated, the signage is not great.

You might make this connection if you are fleet of foot, not much carryon luggage, etc. but I would make alternate plans myself.

Please keep in mind that all of my previous layovers at FRA airport were extensive...3 hours or so and hence I never have missed a connection out of this airport.

Good luck and I hope you make the connection!
