Sent an email to the GT vendor, email listed in hotel directory on p.f.c. and got no response. Sent a follow up and got "No problem, we can get you direct to DUS". Upon landing and block in, our driver didn't have a clue and couldn't take me direct to DUS as he had anoer pick up. I suggested he take me to the hotel with my FO and have another driver pick me up an hour later (I had 4 hrs between block in and departure out of DUS). He didn't think at would work, but after numerous phone calls and walkie talkie conversations, that is what happened. Had an hour at the Dorint and another driver picked me up at 7a for a 925a departure. The ride was 110 euros (bank was not an issue). Delta/AF use the Open Lounge at DUS and I saw no showers or free Internet. Just some snacks and drinks. Overall, was a painless evolution.
