I'm travelling to Frankfurt tomorrow, and just have a couple of last minute questions. I've read that its best to take the train from the airport, but I'm just wondering how easy it is to figure out where to go, which stops to take etc, or if there are any tips or tricks from anyone. Are any signs in English or will it be hard to figure out what I need to do? Finally, about changing currency, is it ok to do at the airport, or should I wait and go to a bank or the hotel or something else. I've neer been there before, obviously, and after flying all night I'm not going to be in the mood for some surprises once I get there. Thanks.
