The Tokyo Hilton is quite a distance from both airports. It is in Shinjuku. No airport shuttle.

I mentioned before that you should go to the limo bus website.

The cost is probably around 3000 yen or maybe more but whatever.

After checking in I would book the bus to Narita for the next day. Go outside and tell the doorman/woman you want a taxi to Kabukicho and say Gojira or Godzilla.

There are restaurants on the side street where you will be dropped off. Osaka restaurant on left has great okonomiyaki. Further on at the corner you can get the tuna sushi combo. At that point or before look up to Godzilla popping off.

Go right at Togo Cinema and left at donut shop. Dunkin’ Donut IIRC. Then down to corner for taxi back to the hotel

Next morning taxi to Shinjuku Gyoen and enjoy the park for a few hours Then back to catch the bus to Narita

Those taxi rides will cost about five bucks each way. Or Hilton has free shuttle to Shinjuku Station or walk

mrwunrfl - I took your advice and decided to stay near Narita that first night and take an earlier flight to Seoul the next day (12:30pm). Here's where I landed for itinerary. Flights are booked, just need to book the Shinkansen along with hotels.

• Arrive in Tokyo (1 night) – Aug 8
  • Fly to Seoul Aug 9 (12:30pm)
• Seoul (4 nights) – Aug 9, 10, 11, 12
  • Fly to Osaka (14:00, Shinkansen bullet train to Kyoto – Aug 13
• Kyoto (4 nights) – Aug 13, 14, 15, 16
  • Shinkansen bullet train to Tokyo – Aug 17 (Schedule ahead of time)
• Tokyo (4 nights) – Aug 17,18,19, 20
  • Fly out Aug 21

Thanks for everyone's help. Much appreciated!
