Just there in November, very limited availability, had to book 1 and 2 nights at a time until I had the 5 nights I needed.
It's a small property. Very well located so worth the effort.
I got MR to straighten it out eventually (after the fact) but there was a lot of confusion between MR and the Grand Flora. English is a challenge with this property in something complex like this.
FYI, had the same issue when trying to combine, I was told is would become an Anytime award etc.
After Jan 15, the property goes to Cat 8, so probably need to resolve by then, who knows how they would handle changes after that.
