I was all set to go earlier this year, I was in Tokyo for business and I had decided to extend my stay for just the weekend, but the start of the war and SARS concerns brought me home early.
For work I stayed (and dined often) at the ANA Tokyo Hotel - GREAT place, they have a bus that goes to TDL (20 min ride). I looked at staying on property and actually had a room booked for TD, I think because oit was a weekend it was considered peak (their schedule is REALLY weird) THe website has alot of info including pricing and hotel information, so that should help you in your planning and pricing. I want to say that the room pricing was around $480 USD per night. The flight pricing was ridiculously expensive, because I was flying on 1 days notice I was "forced" to book first class- company policy was biz class which would've been fine, but they were out so they let me go primo which was awesome. I will try to dig up some info from my expense reports and translate the yen to $$ to give you a better feel for pricing. I am actually hoping to get out there for work again this year, and will absolutely try to get there. My friend's GF went and she loved the Disney Sea (newer of the 2 parks)area. I think this past year was bad too because it was the 20th anniversary of the TDL and 1st anniv of TDS.
