I too went back and forth on this and ultimately decided to pay OOP for the CRT lunch we have planned. In turn, I used the two TS for dinners at Les Chefs and Rose and Crown. I figured since its prix fix anyway, there wouldn't be any surprises paying OOP for CRT versus another TS somewhere else.
I hate to admit it, but I estimated what we would probably eat at the various restaurants, and they easily doubled what the CRT OOP cost was. Also, since you have to pay upfront for CRT, it will be paid for before arrival so I can figure that into my budgeting beforehand.
Hope this helps!
