Doomed,
My wife is from Chiba, where Tokyo Disneyland and Narita airport actually are located. I have stayed at the Manhatten Hotel in Kaihin Makuhari. It is a very nice hotel. It is one train ride to Disneyland. The train takes about 20 minutes to get to Disneyland from this hotel. The Manhatten is one train ride to Tokyo, and is located actually close to Narita airport. The rate is about 135-140 USD per night, which includes breakfast. The Airport Limosine (actually a bus) serves this hotel every hour. It is about 30 minutes to the airport.
There are so many options for you. Too many to list here. If you like, please e-mail me and I (my wife) can give more options and ideas.
