Here's a helpful chart that breaks down regular, high season and voucher pricing.

Of course, it doesn't quite agree with the number I gave for the adult meal, LOL. I called twice (because the first time the CM gave me the wrong amount for the kid's price) and was told $32.51 both times. But, based on the unreliable info I have received from DL Dining CMs (see above

) I would assume the slightly higher $32.91 to be safe.
The vouchers only save money on the brunches, generally, if you are going in peak season.
