Chiara,
Thanks for your question!
I recently
answered a question just like this one. The answer is yes, you can use your
Disney Dining Plan meal credits all day long of your check out day. It does not matter if you have vacated your room, or checked out at the resort desk, those credits do not expire until midnight.
When we visit Walt Disney World we always try to have a fun breakfast scheduled for the last day. It gives us something to look forward to, rather than focusing on the end of the trip. There is that fun time at
Tusker House Restaurant or
1900 Park Fare for the kids to look forward to. I also make a point of using those last remaining snack credits to grab some Disney-themed treats at our resort food court. The kids can have that on
Disney's Magical Express ride back to the airport, as well as for the flight home. It kind of extends the magic.
I hope that this helps! Write me back if you have any other questions!
Have a Magical (and delicious) Vacation!Doug
