depends on the unit you need & # available at each resort (and it's popularity).
1 BRs seem to be available for dates I check when studios are sold out.
in mid April we decided to extend our October trip to 2 weeks. I was able to book SSR studio starting Columbus day for 4 nights. Waitlisted @ AK - Jambo & Kidani. Noticed Jambo came thru when checking my account 3 weeks later - surprised how quick!
Now, i'm WL'd same dates for BLT & BC. Will be shocked if either come thru lol.
Do you see individual days during the time period you could book & waitlist the days you need? that has worked well for me in the past.
ps don't forget to check the website yourself jik something pops up.
