1) There are no wait lists for any WDW eatery, even V&A.
2) They would be IMPOSSIBLE to function.
3) Let's say
. . . one person drops out
. . . WDW calls the 1st on the wait list
. . . they are not home
. . . do you call the 2nd on the list, or wait ?
. . . if you wait, how long do you wait ?
. . . this could go on for days
. . . and cost a lot of extra WDW labor
4) Thus, not realistic.
5) In fact, I do not know of a single public non-WDW eatery that wait-lists.
