That's pretty much it. Some table service restaurants will ask you if you are on the plan before they seat you and some don't. Let the server know (they will usually ask themselves if not told) and they will help you with your options. Counter service and snacks - just tell them at the register, give them your room key and they ring it through. You will get a receipt with all zero's for amounts. The receipt will tell you how many credits you have left.
