When they offered bouncebacks before closure, most of the year you got an offer for the current year. In late August it changed to a
free dining offer for the following year (when that was being done). That was offered for awhile & then changed to a room offer for the following year.
Because they’re just starting this bounceback now & it applies to 2024 bookings, I’m assuming they will continue with it until sometime next year. Possibly until they switch to a 2025 offer. No real info to back it up, that’s just my guess based on how it worked before.
