Im sure I mentioned in my trip report, but I must have just been super lucky in late March. I was able to book a cabana at 31 days out (checked call log), no idea if it was previously all booked and then a cancellation or not.
Then at check in, they realized they booked me a BLT cabana, but somehow there were still 2 open SAB ones out of the 4 so we got to pick. To top it off, they refunded the incorrect BLT cabana and never recharged for SAB.
Totally worth it, even when charged, to have that private spot with some nice perks at the best WDW pool for the day, especially check in day when you may not have a room right away. Having Hurricane Hannahs food and drink delivered to the cabana was awesome. Hoping there’s availability when you call.
