Yep we're definitely sold on Seoul. A very interesting place and the food, once you get over the kimchi, is excellent. We caught the Airport Express coach from the hotel back to Incheon which allowed us to avoid several sets of stairs in the metro ... no lifts or concessions for aged travellers ... if you have a wheelchair it is possible to get some help .. unfortunately we didn't see anyone in one so that we could nab it!
Incheon airport is splendid and huge. The JAL flight left on time and landed late ... 4 mins to be accurate. As per the service was first class even in the cattle pens. The lunch was excellent; as was the malt beer.
U-City Narita hotel transfer coach got us to the hotel in comfort and we were out-and-about for coffee and eats by 6 pm. In all aspects a perfect day's travel.
A few tips for Seoul:
Book a hotel with a coach transfer or on one of the Airport Express coach's route; the metro is fine but the stairs are a pain.
Most, if not all, the signs you want have "English" names/directions and the ticket machines in the metro have an English option ... too easy.
Don't be afraid to say "No chili", when ordering Korean food ... or be prepared for afterburner surprise!
Don't be put off by the large number of old men in the streets, especially at night when you're hunting for food ... they may be tanked but we found them totally harmless.
A little bit of politeness and less western bombast get you what you want with a great deal of smiles.
We thought Seoul was a mixture of Tokyo and Bangkok ... more Tokyo, less Bangkok. The setting, surrounded by mountains is stunning and the modern steel-and-glass exceptional.
To paraphrase MacArthur, "We shall return" ...
It's better to travel than arrive ... then again ...
