I personally think that's a very nice option for some people. Even though we are going to use all of our TS credits for TS, I intentionally have two meals of our 7 night stay with Signature Restaurants so that we aren't always having to stop to eat at a restaurant. I still enjoy touring the attractions and running the parks.
Not exactly, you use one TS credit at a CS location and are entitled to an additional 2 snacks along with you CS meal. This is probably a good thing for those who didn't make ADR's.
