I can't speak for others, but that would work fine for me. I love FOP, but I don't find it to be "intense".... for example, I would not ride something like Rockin Rollercoaster after eating at Boma. Hope you enjoy both experiences!
The ride is really easy and during our June trip we did the Boma breakfast thing at 08:00. We had a large breakfast and we were at Animal Kingdom by 09:00.
