Hi, Lori! So glad the Animal Kingdom Lodge attack plan will work! Now on to Epcot.
You should totally be able to make Illuminations after your ADR at Coral Reef. I'd recommend showing up by 7:00 p.m. so you get seated on time. (Illuminations is my wife's favorite.)
For Hollywood Studios on May 3, Fantasmic is at 9:00 p.m., which gives you plenty of time to dine beforehand. I'm not thrilled about the table service food at Hollywood Studios, but the atmosphere/experience tends to help close the gap.
Sci-Fi Dine-in Theater is a good time for the concept alone.
50s Prime Time Cafe is another one. If you only have one day at Hollywood Studios, I'd recommend saving some time and money by doing a counter service meal instead of a table service meal. Pizza Planet is one of our favorites (we're big into Toy Story.) You can also snack your way through dinner - grab a soft pretzel on Sunset, a cupcake from Starring Rolls, etc. Avoid the turkey leg.
