My friends and I just got back from Walt Disney World. Each day we were there we did 2 TS each day. Granted most days was breakfast and then dinner. But one day we did lunch at Akershus and then dinner at Flyin Fish (Boardwalk). We even had a snack during F&W.
Our lunch at Akershus was on a Tuesday right at noon, just after the breakfast service had ended. It was not very crowded in the restaurant and we took as much time as we wanted. That is the thing with TS, take as much time as you want/need. I never felt rushed by any of the servers at any of the TS restaurants, including the character buffets, where you would expect a quicker turnaround.
Just have fun with your dining choices and enjoy the down time while in the restaurants.
