Sure you have 1TS, 1CS, 1S but that's for eeach night of your trip per person. So when we go for 14 nights with all four of us, we have 14 of each or 56 all together. We find it being way too much food to eat one TS, CS and snack per day so we always book quite a few meals with 2 TS.
So essentially what I am saying is that you can use more than one credit per day. Don't worry about it being worth 2 or 1 TS worry about it being the restaurant you will actually enjoy, good luck!
