One year, with free dining, we were able to use 1 TS credit for the Fantasmic VIP seating package at H&V, which was a good deal more than the regular meal. But those were also the days when you could use a child's QS credit to buy an adult meal (handy when you've got a vegetarian but hungry kiddo who doesn't want to subsist on mac & cheese) and when you got 2 snack credits per person, one to be used on a Starbucks Venti in the morning, one to be used at World Showcase Food and Wine Booths in the evening.
As previous posters said, it's really hard to come out ahead on the
DDP plan now unless you're hitting one of the remaining character buffets that still take only 1 TS credit every single day. At the end of 2019, you could have booked Storybook Dining or Topolino's Terrace with 1 credit. Not true anymore, which, ironically, might make them easier to book, at least. Frankly I hope Space 220 never accepts it.
