I'm thinking about using my Chase CC annual free night cert at one of the IC's in Tokyo this Dec. Trying to decide which property to stay at. I'm familiar with all 4 except ANA IC.

Since I'm a CC holder, I'm Plat. We're 2 adults + 2 kids, and so technically we don't fit into regular guest rooms in Jpn. However, Hilton will usually let it slide by either giving us a king + free rollaway or letting us squeeze into 2 twins. I don't have as much experience dealing with IC in that regard in Jpn. Flying into HND on day of check-in, need to get to Tokyo Sta the day after with wife and 2 kids. Sort of like to get the most value out of my cert, as ridiculous as that may sound.

Here're the pros & cons in my mind for each property:
- Yokohama: love the location & view; not easy to get to Tokyo Sta; sometimes I see this place avail for 15,000yen a night so not getting much value out of cert.
- Strings: easiest to get to Tokyo Sta next day; like the atrium; just an average 4-star.
- Tokyo Bay: nice view; feels more upscale than the above two; poor location with nothing nearby.
- ANA: not familiar with this one (their twin bed is supposed to be only 110cm wide, so I will only consider them if they give us a king + free rollaway).

I guess the biggest factor, which is unknown to me, is what kind of treatment I can expect as a Plat using free night cert. Upgrade? Accommodation for 4th person with a free rollaway? Not expecting free food, of course. I would appreciate any insights/recs.
