If you notice the previous posters said the number of credits you get is determined by the number of nights stayed, not days. We usually take the first flight out of DFW in order to make sure that we get to WDW by lunch and then take the last flight out of MCO in order to get the most time in the parks. We have always been able to use our dining credits as soon as we arrive and also they are good on the last night up until midnight. What this means for us is that we always have to pay out of pocket for a few meals,since we are always at least 2 credits/person short. For people who arrive at WDW late or leave early on their last day, they would not have this problem. My point is that if you are there seven nights/eight days, you only get 7 TS, 7 CS, and 7 snack credits, not 8 of each, so be sure to count your meals and if you are going to run short, figure which meals are cheapest and pay for those OOP, (either that or you could share some meals

).
