There are club rooms on the club floor, but of course rather limited in number.

There was fruit and bread and a miso station each day. I don't think the lounge breakfast is anything to write home about but overall I found the hotel to be a very good deal. We paid 22000JPY per nt plus the fourth night free via Citi Prestige, and applied a DSU to get a suite. For Tokyo -- I considered that a very good deal.

For those with children: the large park across the street has a playground - walk toward the Park Hyatt and you can't miss it. There is a very large concrete slide which my son absolutely loved as well as several other amusements. It was great to have room for him to run around as soon as we arrived at the hotel from our flight from JFK.

Regarding the suite, as others have mentioned there is no real door between the bedroom and living room. Still, it was nice to have the extra room and we appreciated the fruit plate that was refreshed each day. The 7-11 in the basement was also a great convenience for quick snacks for our son, especially string cheese!
