They don't leave until tomorrow.
Reservation is not until Sunday.
I can't believe there isn't a way to do this. I'd rather not just give them a gift card...I'd like the waiter to present them with the bill and says it's already been taken care of.
My MIL did that for us for our 10th anniversary (not at Disney) and 20 years later, I still think it was one of the nicest surprises!
You can't do this at WDW if you are not actually there. Best you can do is find some way to get a gift card to them.
My D recently got engaged and will be at Le Cellier on Sunday. We would like to pay for their dinner as a surprise. Dining reservations says I can't do this. Any ideas?
