Tokyo Disnet Resort Hotels - Good rate?

I don't have a personal experience with the hotels at TDR, but let me ask you: When you say hotels in Tokyo Disney Resort, are you referring to places like the Disney Ambassador that are on-site at TDR? Again, I do not have the direct experience with them, but I have read somewhere that those hotels in season are always expensive, and the only way to get around that is to book a tour through a travel agency like JTB that includes a stay in one of those on-site places.

If you are only thinking about the TDR associated hotels that are not quite on-site but are right by TDR, e.g., Hilton Tokyo Bay, I would check with a site like Rakuten Travel to see whether any rooms are available at a discount (doubtful in high season). When you are there, try the Disney Ambassador Hotel at TDR, just to see whether it shows up.

Disney Hotels - Disney Sea MiraCosta and Disney Ambassador - are very expensive (from 27,000 yen for a twin), as are the six official hotels (Sheraton Grand, Okura, Hilton, Tokyu, Sunroute Plaza - similar price). Cheaper and still within easy reach are the partner hotels (Palm & Fountain Terrace, Ueyasu Brighton, Shinurayasu Oriental and Emion Tokyo Bay - from 15,000 yen for a rwin). If you are a group or a family, Palm and Fountain Terrace are particularly good value as up to 4 adults can stay in a room from 16,800 yen.
Try discount hotel sites like Rakuten Travel (as mentioned), Jalan (Japanese only), and Bestay (Japanese only).

Yes, they are expensive. I think tour operators offer hotel+entrance tickets for a small discount.

Thank you very much for helpful information. I am looking at the very end of October to the beginning of November to visit Tokyo Disney Resort. I wanted to stay in Tokyo Disney Resort as my husband will join me to go there for his first time, and I wanted to make the trip great. Reading your advice, it might be better to stay in one of the partner hotels and have romantic dinner at a nice restaurant in Tokyo Disney Resort... I will check sites which you have given me, as well as local tour operators. Thank you very much again for your help.
