It’s also the end of Presidents week, so I think in combination with the Princess half weekend, the remainder of what was left booked at 7 months.
I’ve been trying to switch a stay I already have booked that weekend to a split stay, so I’ve been monitoring a couple resorts and it’s definitely tough. I have seen single days pop up, more on the second half of the weekend, so you might be able to piece something together (or at least a split stay) if you have enough points to be flexible and book single nights at more than one resort while you check for the other nights. I’d definitely take the 1-BR for now if you’re set on going that weekend!
