I usually stay at the Hilton but not tomorrow night because
1) I don't need another stay for requalification as a Gold but need too many nights for Diamond,
2) I may arrive too late for their shuttle and
3) They are charging too much!
So I booked the Mercure since I have some Accor points but after reading some reviews on Tripadvisor I decided 9,500 yen (room only unrestricted) was too much and booked the Richmond for 7,400 yen (room only) instead. I'll report back how I find the place.
