Arrived today, no problems with flights and best of all no problem at Franfurt Airport and my luggage came all the way through. Staying at the Hilton Imperial, very nice and access to the Executive Suite which provides a light meal in the evening.
I dropped my luggage in the room and took a walk to Old Town which is very close to the hotel.
Tomorrow I have a ticket to walk the wall that surrounds Old Town, so more tomorrow.
