Spent Sunday night here, my second Hilton award stay as a Diamond following a very nice stay at the Conrad Tokyo.

You can find many pictures in the recent timeline of my http://twitter.com/tokyohyattfanTwitter account.

Pros:
Really solid new Executive Lounge. Friendly staff. Great selection of sweets for Tea Time, evening cocktail offerings were good enough to make a meal of, and the lounge breakfast was a good enough subset of the restaurant offerings to make it worth considering. Beautiful design...the outdoor area reminds me of the Hyatt Regency Waikiki. Will be nice once it gets a little warmer.

Great location in the heart of Odaiba. You should be able to get a day or two's worth of entertainment out of the area without ever having to get on a train.

Cons:
Other than the lounge, poor treatment of Diamonds. Asked for an upgrade to a suite at check-in because online availability was wide open, and they steadfastly refused to do anything more than offer paying the difference between a base room. Ended up getting a "Twin Executive", which didn't seem like more than a basic room on a high floor to me. And even Diamonds are forced to pay to use the hotel pool.

Rooms look unchanged since the building's original opening in 1995. A disappointing comedown compared to the fashionable lounge.

Restaurant breakfast was sub-standard. They made me the worst white omelette I've ever seen, hard on the outside and raw on the inside.



Overall, I think Hilton Tokyo Odaiba is an acceptable option for a short stay if you can get it for under 20000 yen or 40000 points a night. But don't expect anything more than the property claims to offer.
