We did it in June. We were trying to see Paint the Night, Disneyland Forever and Fantasmic on the same night. I decided to make my reservation for Aladdin's to insure I could get the later showing of Fantasmic. Dh held our seat for the parade while I picked up dinner. It was quick and easy. I told him I had a reservation, I picked our food and he asked which showing of Fantasmic I wanted (I don't know if that's common or not). I then waited inside Aladdin's Oasis (which was nice and quiet and pretty) and they brought my food bagged and boxed to go. We both ordered the chicken. It was better than I expected, honestly. We ate at our seats for Paint the Night.
It was a little confusing as to where to get in for our FP, but we ended up in a pretty good spot that was pretty empty, so I was happy. It worked for what we needed it to.
