wether you choose to use credits or pay cash entirely depends on the meal/snack you're buying.
Most of us will have a hard time using all of our snacks. But snacks can be used to purchase Goofy Candy Company candies, for example 6oz. sour gummy worms/characters. They make perfect gifts for kids back home. You can find the same online on
amazon or ebay for prices in excess of $15 a pack ... when you can get them for a snack credit at WDW ...
So you'll always be able (have the opportunity) to redeem all of your snacks at the end of your stay, as there are lots of prepackaged food options in resort/park stores. But you need to think about that option on your packing day, which very few people on the
DDP do. (the only reason why we had snack credits left on our last stay was that we were already at our weight limit for the luggage allowance, and we just couldn't pack more, even in carry ons ... but always think of snack items at hotel stores on your last day to finish off your snack credits)
That's why you should choose wisely between using a snack credit and using cash to buy a snack.
for example, let's turn to POFQ where you can find the famed "beignets". A snack credit will get you a pack of 3 which is valued at $2.99+tax OOP.
For that same snack credit, you can get the Ice Cream Cookie Sandwich which is valued at $5.29 + tax OOP.
As a comparison, you can get 6 beignets for $4.99 + tax.
So, as you can see, you might probably want to pay for your beignets Out Of Pocket and get a bigger value item for your snack credit and still have those credits for "souvenir food items".
But in the end it's yours to decide.
For CS meals. Consider that you get a dessert with a CS meal. You can ask to have that dessert put in a clear box to take away. But this will only happen at resorts, because desserts at parks are often impossible/impractical to take away (mousse, ice cream, and very perishable items that won't last through the day in your bag ...)
If you're not going to eat dessert, then it might be a good idea to pay OOP in the parks. (But only if you're 100% certain that you will use that credit later, to have breakfast CS instead of a planned snack for exampel, if not, use the credit now.)
At your hotel you will be able to have a muffin, a brownie, or even a fruit cup as a dessert. You can put those in your room fridge and eat them for breakfast the next day, or as a midnight snack when the food court is closed.
So here again, you need to plan and decide if you're going to pay OOP or with credits
but bear in mind that lots of us do not manage to redeem all our CS credits.
Some use their remaining CS entitlements to go to Earl Of Sandwich to get some sandwiches for the trip, right before going back to MCO
On that chapter, if you're not able to take the dessert in a doggy bag, and you're not hungry enough for dessert, decide if you prefer to pay OOP and take the risk of losing a CS credit at the end of your stay.
But all things considered, it's always best to spend your credits first and then pay OOP if you run out.
Now for TS meals
2TS meals are a very poor value on the Dining Plan.
Only exception, dinner shows like Spirit of Aloha or Hoop Dee Doo, for the sole reason that alcohol is included. So if you like your drink, those are good value on the DDP
Consider the value of your dining plan credit.
It costs $60 per adult (even if you got it for free, it still has a value, the higher value you redeem your credit for, the biggest discount you will have received in the end.)
consider an average snack of $4
consider an average TS meal of $9 for the entrée, $3 for the beverage and $4 for a dessert (only at lunch and dinner)
consider an average value of $1.5 for the refillable mug per day.
the "non-TS" part of your dining plan has a value of $21.5
So, your TS credit has a relative value of 21.5 - 60 = $38.5
so this means that you're losing out if you have a TS meal valued at less than $38
Now consider going to California Grill and have the most expensive items on menu
entrée : Bison Center Cut Strip Loin $50
dessert : the plate of cheese at $20
and a beverage at $3
grand total for that meal is $73
when you pay with your TS credits you use 2 credits valued at $38.5, or $77
so you're already losing a relative $4 but bear in mind that you have ordered all the most expensive items on the menu (and will pay a tip accordingly)
most of the times you will have the $40 entrée and the $12 dessert plus the $3 beverage for a total of $55 when you will pay a relative $77 in TS credits.
Once again if the purpose is to have all meals paid for, then so be it, but if you want to maximise your entitlements (especially if you've paid for the DDP) then 2TS meals are really poor values
some 1TS meals are also very poor value.
For example Ohana breakfast is between $22 and $26 (prices vary by season and weekdays/weekends)
so you might pay your meal $22 with a $38.5 credit.
For those "prix fixe" restaurants with a low value, you might want to consider paying them OOP and save your credit for a more expensive restaurant, and treat yourself with one more TS venue.
But some guests will consider that, since they got free DDP, the value of the meal is irrelevant as long as they can eat for free
but also never forget that free DDP is not free at all. The more expensive the restaurant, the higher the tip, and tip is not included (not anymore)
