you may have already missed the extremely limited window that the Grand Flora has with 7 day standard awards. They are scooped up immediately after being made available on Sunday. In scoring my 7 day std award next July, I had to book 3 days first then call back the next week to make it a seven.
It appears you do not have date flexibility on this (backing up to your cruise). Otherwise you could line up your dates with availability.
...or you could look at it this way...the 200k points you are paying for 7 nights is a lot less than you would be paying if booked after Jan 15.
The other way to look at it....book as much as you can at the standard rate and then pay cash for the nights that are not available or are at anytime rates. Rates are somewhat reasonable in October.
Keep checking back.....and especially on Sunday.
