Our hotel in Sankt Goar is more like a traditional Gasthaus and our room is simply delightful. It is perhaps four times as large as before, we have direct views of the Rhine from all three big windows and the beds are comfortable, though lacking in additional pillows.
The only oddity is a complete lack of curtains aside from net ones so we're up earlier than expected due to the light. It matters not as we're still on Thai time and it's about 13:00 now.
Hotel review to follow soon.
