TTFN3 I would definetly KEEP your early p.s.
In my mind, the main reason to eat a character meal in a theme park is to get inside that park earlier than its opening time.
We had an 8:10 p.s.....enabling us to eat all we wanted (yes...nice and fresh!)...and then get a bit of a jump start on the crowds that pour in starting at 9.
One bit of advice....Kilimanjaro Safaris is by far the busiest and most sought-after attraction in the park....and it is best to do it early. (Animals are most active in morning...some "hide" during afternoon.)
But, safaris is on the exact opposite side of park from Donald's Breakfastsaurus. (Think of the park as a clock....restaurant is at 5 o'clock....safaris is at 10 o'clock.)
As soon as everyone's done with their food, get them out and prepare them for a very brisk walk to safaris. I agree...rushing is stressful....but in this case, you'll be glad you did!
(Enjoy the meal by the way....our kids loved the food...and character interaction was very good. Our camera broke just as I was snapping a picture with my kids and Donald.....so 5 minutes later, the host brought over a brand new camera AND Donald!)
