i'd like to use my HHonors points to stay in Japan. The Tokyo Hilton is 40k a night, but the Narita Hilton is only 10k a night. Is it practical to stay at the Narita Hilton and go into Tokyo each day for, say, 5 days of touring the city and area? I plan to buy a three week Japan Rail Pass. I'll be in Japan from the 29th of June for three weeks.
