Just booked the Hilton for late October. Hopefully opening remains on track. Agree 95k a night is a little steep but staying five nights and transferred Amex points at 1:2.8 during their 40% bonus so relatively good value. Will keep an eye on it in case the point price goes down (or opening is delayed.)
Looked at Roku as well for the five nights but it does seem remote and hard to do day trips to Uji or other surrounding areas.
