Might I suggest not using a TS credit on breakfast and paying for the meal OOP.
Breakfasts tend to be the least costly meal of the day (usually between $20-$25 a person I would guess). In order for the DDP to really have any value the meal you use a TS credit on really should cost no less than $30.
If you are looking to get the best value out of the DDP, I would pay for breakfast OOP. If you are just using the DDP to make life a little easier, then go for it. Durring breakfast, juice is considered the "dessert" of the meal so you still get a beverage along with the juice.
