Craig, I went to Frankfurt at New Year and flew to Hahn as well. I hope you don't think that Hahn is in Frankfurt as it is at least a 2 hour coach journey. Was a fucking pain in the arse.
We pre-booked using TerraVision, they were spot on and was half price compared to the price you pay if you just pay when you turn up.
Yeah i know its well out the way.I checked on the website its 12 euros for the bus to Frankfurt city centre.
