Yes, my PS's were all made daily by 7:05am. If your son doesn't want a character meal try Whispering Canyon or 50's Prime Time depending on his personality.
Also, no PS needed but I am surprising the girls with a "Kitchen Sink" at Beaches and Cream.
Again, depending on your DS we have done desert only at Le Cellier to get the Moose Shaped Chocolate Moose or desert only at Coral Reef for Edible Peanut Butter Playdough. (BTW, the sorbet, though pricey, is fabulous as for Mom and Dad as well as a beautiful visual presentation). We got a table right next to the tank. It was wonderful.
Just a few thoughts.
