Make a list of your hotel needs to help you strike a balance between convenience and price. Decide whether you want to stay at an official Tokyo Disneyland Resort hotel, which is close to the attractions and comes with the opportunity to have all park purchases shipped to your room, or a nearby hotel that's cheaper but might not have the same conveniences. Many chain hotels are found in the area, so if you're a member of any clubs you may be able to get a special rate.
Search websites online for the best hotel and flight deals. Many discount websites, such as Expedia and Travelocity, offer additional reduced-rate deals if you book your hotel and flight at the same time with them. However, these deals are not guaranteed to be the lowest prices available, so shop around for the best offer.
Purchase your park tickets in advance, if you know how many days you plan to spend at the park. These are available on the Tokyo Disneyland website. You can purchase from one-day to four-day tickets, with a lower-priced option of evening-only tickets. Children 4 to 12 can attend the park during the day at a reduced rate; children 3 and younger are free. Adults and children purchasing the evening-only option pay the same fare.
Check your passport to make sure it's up to date. All travelers to Japan are required to have a current passport, along with proof you plan to return to your home country. The American Embassy in Japan adds: "Americans generally may enter Japan for business or pleasure without a visa for up to 90 days. Travelers entering the country without a visa must have a return or onward ticket in their possession, proof of adequate funds for their stay, and be otherwise admissible under Japanese law."
Contact the hotel before you leave if you have any special needs its staff will need to address. The staff might speak English, but it's always better to mention any extra requirements ahead of time to avoid unnecessary situations that will be more complicated with a language barrier.
