What is often cited is to put the value of what the
DDP costs onto Disney gift cards. True no one knows what the DDP value will be but it's hard IMO to think it will be like it was when there was actual monetary value in it, those days seem to be long gone in the rearview mirror but the offers Disney puts out depending on what they are can tweak things on how someone sees the value.
Back to the gift card thing, it does have advantages to allow freedom to eat where you want, not worry about maximizing the plan you'd get as well as if there is left over monies it can be used for souvenirs most especially if you're doing it with a large helping of being convenient the plan is designed to eat how Disney wants to you eat (think like a the House always wins for a casino) not necessarily how many do eat. It's controversial for a reason, while not a right nor wrong per se it's skewed quite a lot to being mostly advantageous towards Disney not the guest.
Also to note is Disney gift cards carry money forward while the Dining Plan is use it or lose it. If you happened to have leftover monies and didn't want to use it on souvenirs you can still keep the Disney gift card with the monies attached for a subsequent trip. In 2022 we used some left over monies on some Disney gift cards from our 2017 trip (we didn't use our gift cards for the two 2019 DL trips) and then in 2025 in September used some leftover monies from that 2022 trip as we had gotten gift cards as gifts back in 2022 to use for that 2022 trip (I believe it was almost $47 left over for that) for a meal at Beak and Barrel.
