I plan about half my TS meals in advance. The rest we either walk up, and usually have a wait, or check with the concierge desk at your hotel before leaving for the parks that day. Last year we had planned an "off" day, went to the desk. The woman recommended Maya Grill at CSR. I had never been to that resort. Turned out to be the best meal of the trip. If we planned everything ahead of time we never would have tried it. I really like not having everything planned, but if there is a "must do" restaurant, get an ADR for that one.
