Good question....I am not familiar with
DDP , learning now beacuse of Promo...I understand that it is based on each nights stay, and technically everything related to a nightsstay is valid until check out time...11am, so to me, if you ate before 11 a.m it should be o.k.,, yet park tix are valid all day/night, so maybe DDP too?H owever, I am just guessing...call CRO at 1-800-828-0228to verify, or WDW-DINE..407-939-3463.
Curious myself...a late flight makes a lot of difference then, wouldn't it?
ETA: Just read on another post that dining expires at midnight of your resort check out date. However, your credits are equal to the number of NIGHTS you have booked...so 5 night stay, = 5 TS and 5 CS credits for each member in your party booked to your room, used during a time frame of 6 days...you would have to spread tour credits out over that time, but they are at least valid the whole time.
