I believe swap changes went into effect on May 31st. For Table Service Entitlements-When available at the restaurant, you can now substitute your dessert for a fruit plate, side salad, or cup of soup. Guests can not substitute appetizers for desserts. I saw a list of participating restaurants online somewhere. But, I think almost all DDP places allow it, esp. if you said your were a diabetic.
We have swapped out for a salad--including tomato/moz (Il Trat) and a fancy one with feta cheese and apples, etc. Many salads at TS are $7-$8. You can also substitute a side (I think) for the dessert at CS.
