We will have a 7 hour and 11 hour layover at the Frankfurt Airport (International) between two long flights. Was looking for a recommendation of the three hotels directly in Terminal 1 (the two Hilton Airport Hotels and the Sheraton). We have a family of four so we have two get two rooms with Hilton or a family room at the Sheraton. Any recommendations of one over another? Would you recommend a club room. Also, if our bags are checked through and we have boarding passes for our flights, how much time should we give to get from the terminal to the gate (through security and immigration)? May try to go downtown Frankfurt for a bit. Any recommendations for a good breakfast or lunch place near where the train would drop of in Frankfurt?
