We did the dining plan once in 2018. It was only because we couldn't swing a hotel discount, so we opted for the free dining. At the end of the trip we still had most of our snack credits and some of the quick service credits as well (which could be swapped for 3 snack credits, giving us even more
). We ended up going to Disney Springs and grabbing tons of non-perishable snacks just to use all the credits up. Our son took most of it back to college after Christmas break and shared it with his roommates. College students will eat anything if it's free!
But I mean no offense to folks that love the DP. I understand that it works for a lot of people and they enjoy the convenience. It just doesn't work for us. I do wish TIW would come back, but I'm not holding my breath. I doubt that's as big of a money maker as the DP is for Disney.
