If you were checking in today, high but not 100% (I believe all but 2-3 of the 11 Standard buildings have either been refurbished or are offline). If you are checking in a few months from now, even higher.
FWIW, I was in an "old" 1BR in Paddock right before the pandemic shutdown, and it was perfectly fine. Unless you really need the extra sleeping space, I don't think it is a make-or-break deal.
