Without knowing your guests,
At MK: Tiki Room, Swiss Family Robinson, the Steamboat(name?), Snow White
EPCOT: Maelstrom, Journey into Imagination, Nemo
DHS: Backlot tour
AK: Prime Evil Whirl. The more "zoo-like" aspects they could see at any local zoo?
At Universal & IOA:
Fear Factor, ET unless they are huge ET fans, Dr. Doom, Sinbad Show, Poseiden Show, Seuss Landing.
You probably already know that the main idea is to get there early and do the most popular attractions first. That leaves time later in the day for the rest and maybe the ones I named.
Honestly, at Universal, you don't have to skip anything. If you're doing one park per day over two days, you'll have plenty of time to take in everything. Depending on the crowd level, you maybe be able to ride everything multiple times.
For the Disney parks, if you're short on time:
MK: Tomorrowland Speedway, Aladdins Carpets
EPCOT: Universe of Energy (just because its very long)
DHS: Narnia, Animation Tour
AK: Dinorama
