On AK days for us, it's really a short park day. We start with a Tusker House ADR's at anywhere 8-8:30, we have a great buffet breakfast. I check in, run and go get fast passes for the safari (5 minutes away), go back and have a leisurely breakfast and then we head of to the safari. With a substantial breakfast and a few snacks we skip lunch and then usually leave the park around 2 to 3pm having done all that we enjoy.
As far as Boma, we love it, DS(13) has always loved it, same with our nieces and nephews from 2 to 10. They have African dishes, soups, salads and dressings for the adventurous eaters both adult and children alike and then they have your typical American fare, beef roast, chicken nuggets, spaguetty , pizza, french dries for the not so, adventurous eaters. The food is fresh and flavorfull, we love it but only you know what your family likes and dislikes. My only complaint was when DS turned 10 he became an adult and was charged full price, of course then he ate very little, now at 13, 5'11 he gets his fill and I don't object to the pricing as much.
