If you know you will purchase the regular dining plan, then a spreadsheet is going to just be a lot more work for what you probably already know. Dining plans are best used for the most expensive meals and/or character meals. Alcohol is also now included for the adults in your party. Even if we make advance reservations for various restaurants, we generally have no idea which entre we might want to pick that far in advance, so there is probably a limit to how much planning is practical.
