Looking at your countdown clock it seems you will be at WDW at one of the busiest times of the year. As such, I REALLY recommend making at least one PS/day to insure that you have a place to sit down and eat. The crowds can be enormous and when you are hot and tired the last thing you want to do is wait forever to be seated in a restaurant. Look at your plans and see where you plan to be each day. Maybe plan a breakfast one day, a lunch another, a dinner the 3rd day, etc. That way you will not feel like you are "a slave" to your PS but will have an "ace in the hole" re dining each day. Other options are to eat at off hours (at 11 a.m. or 3 p.m. or 9 p.m.) when there will be less competition for a table. If you are driving and can dine off site, that opens up a lot of choices not available to folks without a car. Truly, if you are traveling with kids, I would strongly recommend PS. I have 4 kids (and a husband who sometimes qualifies as kid #5) and there is nothing worse than a hungry, hot and tired family with no place to eat........
