What you get with a Dining Package over a FP+ is the potential ability to book a 4th FP+ when you use your first 3. The ROL FP+ ties you up because you cannot book 4+ until your first 3 are gone. Last time we went to AK, by booking extra FP+ after our first 3 were gone, we were able to get second sets for Safari, Everest and Kali, plus Primeval Whirl when there wasn't a huge wait but it still saved us 20 minutes...
